The Model 610 Raman spectrometerwas designed to detect chemicals,biological materials and explosivesin the field or laboratory. This analyzercan be used for liquid or solid materi-als and powders. A 50 mwatt laser isused to excite the sample and the dis-persed Raleigh scattering is detectedwith a CCD and displayed on the ac-tive matrix OLED touch screen display.Raman is an excellent fingerprintingtool to identify unknown samples viacomparison to a built-in library.It has an internal calibration mode toensure that it is working properly. It hasa rapid acquisition mode wheresamples can be acquired in < 3 sec-onds. The library and sample spectracan be easily compared on the display.

The 610 is designed as class 1 lasersafe (with a sealed/interlocked cover)identification of materials. Materials canbe stored in vials for on-site identifica-tion and later validation in the labora-tory.

PID Analyzers, LLC hasbeen developing portableanalyzers since it started in1973. We developed the firsthand held photoionization(PID) analyzer for industrialhygiene. More than 30,000 ofthese PID’s have been sold.Today we offer portable PID’s,FID’s, IR’s and electrochemi-cal analyzers. We also manu-facture a portable gas chro-matograph and we are intro-ducing a portable RamanSpectrometer to our field por-table product line.

The model 610 is designed for pointand shoot operation. Samples, evenin thick glass containers, can bemeasured on-site. There is littlescattering through the glass so thesample spectrum is not distorted.

The Model 610 is packaged in asolid aluminum body for ruggedlong lifetime operation. It does nothave a point laser focus that cannotinterpret mixtures or struggles withpellets and other shapes; it featuresa unique Orbital Raster Scan(ORS™) technology that easilyanalyses mixtures and shapedsamples. This high sensitivitydetection system requires only veryshort analysis times and it displayseasy to understand results on itshighly visible OLED touch screen.The resistive touch screen permitsthe 610 to be used in the fieldwithout any problems. The 610’s11 hour operational time using 2-AA batteries offers flexibility in thefield during long operationalmissions where rechargingbatteries is not possible.

The ORS advantage with a hetero-geneous threats in a medium isillustrated in our ORS diagram. In aconventional spectrometer with atightly focused beam may producepoor results or miss the targetthreat completely. We illustrate thisat the top of the diagram. Thisleads to false negatives. Increasingthe laser to a large spot size in aconventional system would requirethe system to have poor spectralresolution. This fundamental lawof optics means that, just like thespread of the laser light over alarger area, the valuable informa-tion about the material is dilutedand spread over the detector. Thisis illustrated in the middle of thediagram; this leads to false identifi-cation. The only solution is to keepthe tightly focused beam andincrease its apparent size by araster system. Our ORS does justthat and is illustrated at the bottom.

Many threat identification applications are difficult due to weaksignals from an unknown material. Conventional handheldchemical identification systems require the laser spot to be tightlyfocused in order to create enough signal to identify a material.The 610 with the ORS technology interrogates a large areaquickly to average over mixtures or curved surfaces to producea highly confident material identification.
