4-channel Segmented flow colorimetric nutrient analyserAmmonium Gas diffusion fluorimetric analyser:

Nutrients – JC068All micromolar nutrient data for CTD’s, Underway and Benthic experiments are all complete, QC’d,

and submitted to BODC where required.Micromolar Concentrations for Nitrate, Nitrite,

Silicate and Phosphate.Ammonium nanomolar concentrations all complete

and available from myself at PML. email me !

All the micromolar data are now cross calculated against certified nutrient reference materials supplied by KANSO Technos of Japan with the certification carried out by the Metrology Research Institute in Japan. Data quality and

comparability is important !Please delete old files and numbers and use these final ones

rather than those earlier preliminary ones.

But if you find any numbers that look wrong/strange then get in touch with me and I can do check on the original analyser

computer files. Some bottle misfires I may have included by accident, always check.
