Hello list, I am having an issue with my GV Isoprime/eurovector EA CF-IRMS.
I just finished running for carbon in plant parts and switched to nitrogen.
This usually is just a change of the ref gas and a change to the nitrogen
project in Masslynx. How ever after a few partial trays, I can not get Data
processing to acknowledge the TCD trace. I can see the trace in the Aux.
chromatogram and in the Data Processing "diplay data" window. As far as I
can tell nothing has changed in the Auxiliary detector parameters. I have
double checked the timing of the peaks and they match the times set for the
Peak ID ( two lines; one with the time of the beginning of the peak and
labeled nitrogen, second with the time of the end of the peak and also
labeled nitrogen). Is there something else that controls where the program
looks for the TCD peak? Any ideas would be helpful. BTW, the isotope data
looks great! Cheers Aaron
