Hi there, I noticed recently that the ECD back signal on Agilent GC 7890 (using it for trace gas analysis) is oddly spiking (while the FID is a straight, consistent line). It never used to do this. I just recently changed the inlet septum, could this…
Our micro GC 990 is Natural Gas Analyzer B and B extended version with 3 channels (PoraPLOT U, 6-meter CP Sil 5 CB, CP-Molsieve 5A). We are having trouble with data processing. We have 2 calibration gases from Agilent (Natural Gas mixture and Universal…
Hi!
I still need help yes, please!
- On the machines (GC system and Injector) it just says HP6890 (see photos attached)
- The PC we employ is an old Windows XP running one, that was used to run the GC-FID before we want to control it with the serial…
Hi, I would suggest to test the same without column installed to the FID. If problem looks similar check for leaks at the FID gas lines and clean the FID. If not clean the inlet and replace the split vent line and filter. Maybe try a new column.

the abundance of ion 69. I rechecked the source and it doesn't look dirty. then I did an autotune it stopped on the width mass axis of the second quadrupole.
Finally, after 2 or 3 more attempts, I ended up completing the autotune with an abundance of…
