Initialization Procedures for a Minicomputer Based Automated Emission Spectrographic Analysis System

Equipment: Spectrographic, developing and recording facil- ities should be equivalent to those described by Helz (1973). The data acquisition system includes an A/D converter, a Hewlett-Packard 2100 minicomputer with 32K of memory, a tape drive, a disk, a line printer, a CRT and a plotter.

Spectrographic Procedures: Arcing and developing procedures should be comparable to those described by Dorrzapf (1973).

Programming: All programs are written in Fortran IV orHewlett-Packard Assembly Language. They are designed to be run under a Real Time Executive Operating System (RTE-II). The programs are modifications and extensions of the Spectrographic analysis programs described by Walthall (1974) and Thomas (1975).

I. Create the Permanent Disk Files:

The purpose of these files is described in the section entitled "Creation of Disk Files". The format and eventual contents of these files is described in Tables I and II. Use these file manager commands to create the files on the peripheral disk (Lu

a) Create the % transmittance files, TVFLA and TVFLB

:CR, TVFLA::-12:1:712:CR, SAVI::-12:1:8:CR, TVFLB::12:1:712

b) Create the line finding file, LNFNWA

_ :CR, LNFNWA:::1:2344 (for 24 samples + 2 Fe) or :CR, LNFNWA:::!:3472 (for 36 standards + 2 Fe)

This file is renamed LNFNWB after all the spectra on a plate have been recorded, and LNFNWC after the file for the magnetic tape (containing line finding and preliminary answers) has been composed. LNFNWC is renamed LNFNWA by the program "DATA". Therefore, it must be called LNFNWC if "DATA" is to be run and LNFNWA if the recording program "MOOR" which follows DATA is to be run.

II. Load the Programs:

Figures 1-3 shows a which programs are used.

Ais to

which each program requires and the files it uses brief description of the function of each program included. There are not enough blank ID segments have all these programs loaded at once, therefore the wavelength table generation set of programs is loaded when the wavelength tables need updating, the standard- ization package when graded standards are run and the analysis package when natural standard rocks or samples are to be run. Special purpose programs like STATS, EPTAB, COLLT, and CREPT can be loaded as needed. A trans- fer file on disk or paper tape utilizing the file manager commands to OF (off) or RP (Replace) a program is probably the best way to bring programs in and out of the system.

III. Wavelength Calibration:

A. Record several iron spectra ?or each spectrum:

1. Position the scanning microphotometer at the low wavelength end of the spectrum before the Fe 2332 & line.

2. Set the ready flag in the % transmittance file with the command "ON, FIXA".

3. Schedule the recording program with the command "ON, MOOR, NOW". When the question "RECORD?" appears on the CRT, reply "Y", then push the record button.

4. The program will halt after the spectrum has been recorded and the A/D converter voltage readings have been converted to % transmittances The message "SPECTRUM RECORDED:FILE 1" will appear on the CRT along with an error message indicating that the computer has insufficient information to find specific spectral lines.

5. Print the contents of TVFLA on the line printer using the file manager list command "LI, TVFLA". The program FIL1 may be used to list only particular records from TVFLA.

oB. Calculate the dispersion in readings/A:

1. Using the reciprocal linear dispersion of the spectrograph in A/mm and the sampling rate of the scanning microphotometer in readings/mm calculate an approximate dispersion in readings /A.

2. Calculate the expected reading numbers of the Cd fiducial lines Cd 2748 A and Cd 4415'A and the windows around them, using their wavelengths and the dispersion calculated in "I".

3. Find the Cd lines in the printout of the trans- mittances file TVFLA or B. Remember that there are 128 transmittances per record starting with record #2. Improve the estimated dispersion based* on the actual location of the Cd lines. The exposure time of the Cd lamp may have to be adjusted to give well defined lines with narrow (1 reading wide) maxima.

4. Find the Fe 2332 A line. This line is designated as having a zero estimated position. All other estimated positions are relative to it. The zero estimated position in the program is the number of readings into the recording at which this line is found.

5. Using this dispersion estimate calculate an estimated position in reading numbers for approximately 220 iron calibration lines evenly spaced throughout the spectrum. Search the % transmittance file printouts from several spectra on several photo- graphic plates for the iron lines. Adjust the estimated positions of the iron lines .if necessary.

6. Dispersion should be uniform across a wavelengthregion and in all positions on the plate. Iron lines should be found within 2 readings of their estimated positions (calculated in 5) + the reading number of Fe 2332 A (zero estimated position) + a spread correction based on the separation of the cadmium fiducial lines differing by more than 2 readings from their usual separation (based on the findings in 3).

C. Create the Wavelength Tables:

1. Create ABCLAL using the interactive editor. Enter the element symbols, wavelengths and estimated positions of the iron calibration lines into

section I according to the format described in Table III. Follow the iron calibration section with a section containing the element symbols and wavelengths of the analytical lines according to the format of section II of ABCLAL as described in Table III.

2. Edit programs DRCT and DATA to contain a 2 step filter factor and information for finding Cd lines appropriate to the spectrograph used.

3. Create a temporary version of TECLAL and WLCLAL (described in tables IV and V) by scheduling the program WLTB with the number of iron calibration, NFE,and analytical lines, NEL, as parameters, e. g.

"ON, WLTB, 220, 450"This program series will also create the file SREPRT (described in Table VI) which correlates all the lines for each element regardless of wavelength. SREPRT also contains default head- ings for a sample report form.

4. Calculate the estimated positions of all the analyt- ical lines in the file created in step 2. by scheduling the program CEP, with the number of iron lines (NFE), and the number of analytical lines (NEL), e.g.

"ON, CEP, 220, 450"This program will write the calculated estimated positions into file ABCLAL.

5. Create a final version of TECLAL (Table IV),WLCLAL (Table V) and SREPRT (Table VI) by purging the temporary versions of these files and re- scheduling WLTB with the number of iron lines and the number of analytical lines:

"*ON, WLTB, 220, 450"

IV. Emulsion Calibration:

1. Adjust the filter combination at the entrance to the spectrograph so that the transmittances of the analytical lines fall within a useful transmittance range. (2%-80*).

2. Adjust the burn time of the iron bead so that the % transmittances of the iron calibration lines, when viewed through a split filter, are distributed over a wide range in each plate emulsion calibration curvg (PECC). The plate emulsion is calibrated every250 A, 10 PECC's cover the wavelength region 2250 & to 4750 A. Each curve uses 26 lines the % trans- mittances of which should be equally distributed in the ranges 80%T.

6. beiect tne nnes to oe usea in eacn rnuu. Line* be used in 2 adjacent PECC's. Edit program PECC so that the variable "NA M in the data statement reflects these choices.

V. Concentration Calibration:

A. Standards1 . Up to 36 standard spectra can be recorded on each

photoplate.2. Identify the standard and relate concentrations to

spectra by scheduling the program called DATA. Answer all the questions which appear on the CRT. The concentrations related to each standard spectrum are stored in the computer in "JP" type files (described in Table VII). The file name is made up of a 2 digit page number. The JP type files are designed primarily for samples and so Table VIII describes a lot of information which is irrelevant to standards. Respond to the question "STANDARD CONDITIONS?" with "NO". "KOC" equal's 21 for standard plates. Concentrations are coded into the sample numbers as a 2 digit exponent, 0, 3 significant digits of the concentration. The exponent represents the power of 10 by which the 3 digits must be multiplied to give concentration in ppm*100.

ex. concentration sample #

68. 1% S-050681For each spectrum the computer displays the file #, exposure #, field #, sample # and factor on the CRT. File #, exposure #, sample # and field # (optional) are automatically incremented from 1 spectrum to the next. The computer prompts the operator with a colon. If the displayed line is correct answer Y. If it is incorrect put a "/" under each correct character, and the correct character under each incorrect character. After the last correction, end the line with a semicolon. The computer will display the corrected line and prompt the operator's approval with a colon. Answer "Y" or make further changes.

The Data program automatically schedules the record- ing program MOOR. When "Record?" appears on the CRT answer "Y" and push the record button.

The Data program automatically schedules the record- ing program MOOR. When "Record?" appears on the CRT answer "Y" and push the record button.

Cd line finding will be done automatically. The program displays the reading number and %T of each Cd fiducial line and the spread correction between them. It then asks if the operator wishes to change parameters. Answer "N 11 if the lines are found correctly, otherwise answer 5I Y" and change the parameters to find both lines correctly.

The computer automatically schedules the standard- ization program package after all the spectra have been recorded. This program asks what element is in the standard. It then prints a page for each line of that element listed in the analytical lines section of ABCLAL. Figure 4 is an example of this printout. This page contains a tabulation for the line, through all the standard spectra on the plate, of the % transmittance of the line peak and background and of other lines in the vicinity of the line. The tabulation also includes concen- tration, relative intensity, and a comparison of where the line was found versus where it was ex- pected. The computer calculates first and second degree coefficients for a least squares fit of relative intensity versus concentration. It then assigns limits to the analytical curve based on the slope of this curve and the relative intensities of adjacent points. It lists the points used for the final curve alone with the coefficients of a least squares fit of the points between the computer selected concentration limits. It evaluates this final curve for slope, fit and number of points. It also suggests lower limits which would discriminate against spurious peaks with a confidence level of 95% and 97%.Finally it prints a summary sheet (figure 5) for all the lines of an element which tabulates wave- length, priority number, new and old concentration limits, coefficients of the newly fitted analytical curve, evaluation of the curve and a suggested lower limit based on a signal to noise ratio of 2.

File "ABCLAL" should then be amended using the in- formation on the summary sheet for each element and the individual sheets for each analytical line. Line priorities should be assigned based on sensi- tivity. Files "TECLAL", "WLCLAL", and "SREPRT" should be purged, program "WLTB" should then be scheduled to regenerate these files with the up-dated information in "ABCLAL" and to print a revised concentration range table.

6. Future additions to the standardization program include a program to automatically update a duplicate copy of "ABCLAL" with the information in each elemental summary sheet. This will minimize manual editing and the chance for transcription errors. A program which plots the analytical curves by an on-line plotter is also planned.

B. Natural Standards

1. Select 20 well analyzed standard rocks which cover the range of rock types most likely to be analyzed, The results from these rocks will be used to adjust the priority order of the analytical lines and their estimated positions. Interference treat- ments can be devised based on answers from these rocks. Several of the natural standards, which most closely match each set of samples should be included on each plate to monitor arcing, develop-' ing and plate recording conditions. Each analyst should arc duplicate plates containing all 20 standard rocks. The programs are set up to expect duplicate plates from three analysts.

2. The plates should be recorded as if they were sample plates, the only difference being that no inter- ferences would be in the wavelength table i.e.,

*ON, FIXA (to set the "ready" flag in the transmittance files)

*ON, DATA (to enter plate and rock identification data).

These programs will automatically schedule the re- cording program "MOOR" until all the spectra on the plate have been recorded. Then the programs for plate emulsion calibration, transmittance to intensity conversion, answer calculation, report form printing and storage of line finding and preliminary answer information on magnetic tape for future paper print out or microfiche processing will be scheduled automatically,

3. Compare the answers calculated from each analytical line for each standard rock on each plate. Create a file LNFNSV in which to store the pertinent data from LNFNWC each time a plate is recorded i.e.,

:CR,LNFNSV::-12:1:1446

10

After each plate has been recorded and the spectra have been analyzed run the program COLLT with a parameter which tells which of the 6 standard plates has been run i.e., for the fourth one of six:

*ON, COLLT, 4Next, using the interactive editor and the report form correcting program "CREPT", make two report form files named "ROCK01" and ROCK02". These files should be in the same form as Table V, and contain the accepted values for the standard rocks. If no accepted value is available print an " = " in the place for the concentration for that element and rock.

After the six standard rock plates have been recorded run the program "EPTAB". This program collects all the answers for a particular line and standard rock from all six plates. It uses * "ROCK01", "ROCK02" and "LNFNSV". The results are presented in a table for each element such as that in figure 6, where the column headings indicate the standard rock, and the accepted value of the element in that rock. Each horizontal section is identified by the wavelength and con- centration range of a particular analytical line. The six answers calculated on the line for the same rock are reported along with their averages.

This printout is useful for assigning priority numbers to all the lines of an element. Sensitivity and freedom from interference should be considered when assigning priorities. The print out is also helpful in developing interference treatments (sections III and IV of ABCLAL).

A second printout, an example of which is shown in figure 7 is also produced by the program "EPTAB". This printout shows where a line was found in respect to its estimated position for all the rocks, which had accepted values within the concentration range of that line, on all 6 plates. This print out is helpful in adjusting the estimated position.

Update the line priorities,estimated positions and interference treatments in file "ABCLAL". Purge files TECLAL, WLCLAL and SREPRT. Run the program WLTB with the number of iron lines, the number of analytical lines, the number of sub- traction type interference treatments and the number of priority change type interference treatments- i.e., ON, WLTB, 220, 450, 56, 31 An updated concentration range table will be printed

5. Statistical study of the overall precision and accuracy of the method as well as differences between analysts. These programs assume duplicate plates arced by three analysts.

a) Re-record the standard rock plates using the updated wavelength tables with inter- ference treatments included.

b) Use the program "SHIFT: to arrange twenty report sheets, one for each standard rock. Each report sheet must contain the duplicate runs in adjacent columns for each analyst. The seventh column contain the accepted values for this particular rock.

c) For each element on a report sheet the program "STAT6 11 calculates the mean of the six determinations and compares it with the accepted value to get the percent deviation or accuracy. The precision is reported in , two ways:

i) The analytical error of the method, excluding differences between analysts is computed from the three sets of duplicates.

ii) the standard deviation of all six de- terminations is calculated. The ratio (F) of these two variances should not exceed certain critical values if there is no difference between the precision of the analysts at a 95, 97 or 99% con- fidence level. (Youdin 1951).

The program also pools the variance based on the difference between duplicates of all the answers on the report form. This data can be pooled with similar data from the other standard rocks to give some measure of the precision of each analyst. Figure 8 shows a sample print out

VI. Sample Analysis:

Samples are recorded in the same way as standard rocks. Identification data for each sample on each report form is entered by answering queries on the CRT from the DATA program series. Samples may be identified by sample number (assigned by the laboratory), field number (assigned by the geologist), exposure number (referring to the spectrum on the plate) and file number (referring to the order in which the spectrum was recorded. Between one and ten samples fit on each report form. Samples may be placed on report forms in any order, regardless of the order

12

in which their spectra are scanned. Each report form contains the results of 64 elemental determinations per sample. The ten major elements are also reported as oxides. For the computer's purposes, report form files (OP) are stored by job number (4 characters) and page number (2 digits) and are in the format shown in Table VIII. Standard report form headings are copied from file SREPRT (Tables VI and VII). Report forms are also identified by submitter, analyst, date, spectrographic 'lab number and sample control billing number.

Samples are recorded in the same way as the standard rocks. The standard rocks recorded on each plate to monitor conditions are reported with a page number of 98, and with sample numbers starting with S- and ending with a 2 digit code identifying the standard rock (Table IX). The computer compares the reported answers for Si, Al, Fe, Mg, Ca, Ti, Co, Pb, Zr with the accepted* values and prints out a message if they are not within a step. These elements have been chosen, because of their abundance in geologic materials, their differences in volatility and the wavelengths of their analytical lines, to monitor conditions in the arcing and developing stages of the analysis procedure. The computer also prints out the total oxides, the effective arc temperature and the electron pressure for each analysis. Temperature measurements are based on the relative intensities of five iron lines and electron pressures on the relative intensities of 3 pairs of Titanium ion/atom lines (Golightly, et. al., 1976). Report forms and temperature, electron pressure and standard rock information are printed on the line printer within 5 minutes of when the last spectrum is recorded. A magnetic tape (9 track, unlabeled, ascii, blocked in 6650 character records)is also written. This tape contains the information stored in the disk files JP and MTAPE (Table X). The tape is used with an auxiliary program written to run on the IBM 370/55 to produce a magnetic tape suitable for the Quantor microfiche equipment. Thus within 24 hours a series of microfiche are generated for each report form. The microfiche contain a copy of the report form, the plate emulsion calibration points and coefficients for each PECC, and the transmittance of the lines used for the plate emulsion calibration in the light and dark steps. The microfiche also contains preliminary answers calculated on all the analytical lines in all the samples and the transmittance intensity and interference information for these lines.

13

The fiche are indexed by job and sample number and type of printout. The title also includes submitter, analyst plate number and date. Thus the analyst has detailed information about all the analytical 1 ines when checking the report forms. The program "PTAPE" can be used to print data on the magnetic tape directly on the line printer for immediate perusal. Alternately, the program series "MFICO"can be used to print data on the line printer directly rather than on magnetic tape. Should report form correction be necessary the program "CREPT" uses the Hewlett-Packard interactive editor to amend report form files. Extra copies of the report form can be printed by scheduling the program "WREPT" with the job and page numbers in octal, for example to print a copy of JOB number AB01 page 02:

*ON, WREPT, AB, 30061B, 30062B

The completed analyses can be arranged by sample number followed by 64 elemental determinations followed by the next sample number by the program "RASS". This program prints a 9 track, unlabeled ASCII tape, one file for each report form, blocked in 20 character records. An IBM 370 utility program is used to copy this tape onto a disk accessible to the Rock Analysis Storage System.

Creation of Disk Files

1. Transmittance Files (TVFLA, TVFLB)

These files should be created first because they are constrained to start on track and sector boundaries by the throughput driver, DVT77, which stores data acquired by the A/D converter into disk files. The first record contains information necessary for find- ing lines and backgrounds for the spectrum such as a flag indicating whether data reduction is complete, the transmittances and locations of the cadmium fiducial lines and locations of the cadmium fiducial lines and the spread correction, fog and the reading number of zero estimated position. Records 2-712 contain 93.000 transmittances covering the wavelength region 2300A - 46608 in 2508 intervals.

2. Wavelength File (ABCLAL)

This file has three sections: iron calibration lines, analytical lines and entries for up to 3 different types of interference treatments.

a) The Calibration Section-contains the wavelengths and estimated positions of the iron lines in wavelength order.

b) The Analytical Section - contains the element symbol, priority, wavelength, concentration range, estimated position and analytical curve coefficients of each analytical line. It also contains information for line width measure- ments, and monitor lines.

c) The Interference Sections - supply information for subprograms IGS, IPC, and for future development (in that order). Entries in each section can be arranged in any order.

i. IGS is a subprogram which uses a straight line relationship between interference concentration and erroneously reported additional analytical concentration to subtract interference effects. The entries identify the analyte, the inter- ference and the coefficients of the straight line.

16

ii. IPC is a subprogram which facilitates temporary answer selection from an analytical line other than the one chosen by the computer based on the priority scheme. The entries identify the analyt- ical line subject to interference, interference conditions which must be met and characteristics of analytical answers affected by the interference.

3. The computer automatically converts the acii wavelength file ABCLAL into a binary file TECLAL.

4. It then creates a new type binary file, WLCLAL, in which it stores like words in contiguous records, i.e. all the estimated positions for a given section are grouped to- gether, all the lower concentration limits together etc.

5. Standard Report File (SREPRT)

The computer creates this file using information gathered from WLCLAL. It includes a tabulation of the number and priority type of analytical lines for each element and a correlation between the order of lines on the preliminary report form and in the wavelength table. It also includes textual information for the final report form and default parameters for the emulsion and wavelength calibration.

6. Line Finding File (LNFNWA, B or C)

This file contains data pertinent to the plate being recorded, such as transmittances, intensities, error codes, concentrations and the number of readings away from its estimated position at which line is found in each spectrum. It also contains the number and names of the report form files generated for each plate and the element concentrations to be reported. The file is called LNFNWC when it is not in use. When the identification data for a plate is entered by the program DATA the file is renamed LNFNWA. When all data acquisition is complete the file is renamed LNFNWB and when all the information necessary for the microfiche record of the plate has been transcribed into the disk file (N or) MTAPE the file is renamed LNFNWC.

17

7c Report Form File

This file is automatically created by the computer. The name is constructed from the Job Number (4 characters) plus page number (2 digits). It contains the text for one report form as well as the file numbers corresponding to each of the samples which appear on the report form.

8. Magtape File (MTAPE or NTAPE)

This binary file resides on the disk and contains all the information to be recorded on to microfiche for one plate. This information includes emulsion calibration points, line finding for all the spectra and preliminary reports for the sample spectra showing the preliminary answers calculated on all the analytical lines.
