We ran into problems with the GC today. It looks as if some of our analytes are being degraded in the inlet more and more each injection. From the Friday of week 5 to today I can see a definite progression of either lost or smeared peaks for several analytes. It is most noticeable for propanil, fipronil, dimethoate, and DDT.
Most of my time was spent working with Anna on interpreting chromatograms, manual integrations, compiling data into a raw data master spreadsheet for data work-up, and general troubleshooting of the inlet problems. The other staff, especially Adama were observing the training as well.
Adama and I vialed up new standards specifically for the retrieval 2 samples and set up a run on the GC over night. Anna should be working on reviewing the run tomorrow and updating the calibration table.
