*The system and method are given at the bottom of this post*
I am working with an Agilent 8860 operating a DB-624 UI (30m x 0.25mm x 1.4um) column with nitrogen carrier gas and split inlet (20:1). The system was shut down for approximately 1 year, and…
Hi Community
I have an Issue on one of our GC-FIDs 6890N. I have large Peak Tailing, especially on the back of my chromatogramm:
What i already did:
- New Column
- New Septa/liner
- New Gold Plate
- Cleaned Inlet and Detector
- Re…
Hi everyone.
We have a 8890 Agilent GC with nickel catalyst and FID detector. We would like to use hydrogen as carrier gas, but we don’t know the right flow rates, because the manual is indicating flow rates only for using helium as carrier gas.
For…
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 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…
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.

Any special procedures to prepare for cross-country shipment a 7890B with SS, PP inlets, heated valve oven, and TCD-FID? Also a 7697A with 100-vial tray?
I have a gas-phase reactor system that uses the FID of a 7980A to analyze the product mixture. Currently, I have a pressure buildup (up to 30 psi - the carrier gas delivery pressure) when the system is stationary. When the gas sampling valve actuates…
I have a 6890N GC with dual FID. The back column has a much higher flow rate than the front column. The two columns are identical and the setup for inlet, column and detector are identical. I have also swapped the EPC's between the two detectors. Seems…
