It is a capillary, USP 401 The gas chromatograph is equipped with a flame-ionization detector, maintained at a temperature of about 260°, a splitless injection system, and a 0.53-mm × 30-m fused-silica capillary column bonded with a 1.0-µm layer of phase…
Slightly related: As part of a new lab setup, I decided I could greatly save having to replace cylinders if I ran my FID on a one-fifth flow of pure oxygen instead of compressed air.... Maybe you could guess the result. Every ignition was a detonation…

Hello howard_sanford ,
I tried clearing the preferences for IDBrowser, and it did work when I used the old PCDL, but the "m/z" column in ID Browser did not show anything. So, I did it again and for the second time, the m/z of features showed up, but…
I got a data sheet for my Agilent 7890 FID detector. The stated linear range is 10x7. This range I think should mean that from 1% down to 0.1 ppM the detector is linear for Tridecane. I figure concentration-wise in splitless mode - that works out to be…
Hello, We are using Agilent 7890B GC/FID with Headspace sampler. There is a problem in FID unit of the system. In FID parameters, Temp is 220 C, H2 fuel flow is 30 mL/min, Makeup flow (N2) is 25 mL/min, He flow 1 mL/min. These are setpoints and actuals…
Hello everyone, This is my first post and I'm excited to have discussions for this thread. I wanted to start off with a small introduction with some of my experience. I have 4 years of experience in operation, maintenance, method development on the following…
In my experience, usually when a method fails to download to a 7820A GC it means that one of the zones on the GC is in a faulted state. This does not always get reported in the instrument actuals in ChemStation, so the best way to double-check this is…

Hello,
We have a GC 7890A model equipped by tray (SN#CN90452624) and Autosampler (SN#7683) I am receiving the following message while trying to run sample followed by a shaking arm and beeping noise. Any help on what might cause the problem is greatly…
