Hi! Recently we baught GC 8890 with tandem detector fid-scd(detector for sulfor detection 8355). In this case limit of detection of sulfur compaunds is very high (ppm level). We need to meet more low limits of detection of sulfur compounds. Can we dismount…
I am having difficulty with lighting the FID on my 5890 GC. I took apart the detector and cleaned as best as I could. I removed the jet and cleaned it on a sonicating bath. However, I am still unable to thread a syringe cleaning wire through the jet.…
Hello igorvlad
I’m sorry for the delayed reply to your message. Do you still need assistance with this? If you do, please take into consideration the notes below. However, if the issue was resolved, could you please share what the resolution was?…
The GC Calculators and Method Translation Software (MTS) is available for download from Agilent.com . The package includes:

Hello and Help!
My GC-FID's inlet pressure stays at 0.7 psi and does not reach the setpoint of 10 psi. Makeup gas reaches the 25 psi setting. Liner and septa are fine. I unscrewed the inlet column nut and placed my finger at the bottom of the inlet…
The basic tools I would recommend to have for GC maintenance:
Ceramic column cutter
1/4" wrench (column nuts)
7/16" wrench (gas fittings at back of GC)
1/2" wrench (replace gold seal on S/SL inlet)
Torx 20 driver (removing FID collector assembly…
Hi Dr. Know
Here is some of the information you have requested. Please let me know if you need any further info.
How is your system configured? FID detector using helium as carrier gas, nitrogen as makeup gas.
Which phases are the two columns…
Hello from Kazakhstan,
Very interesting theme.
I also have some issues with flow method correction and some questions.
1) We use Excel CFT calculator. So how much pressure we should put on calculator, when using SCD detector with FID? As calculator…
I'm going to be calibrating for ethanol on my HS-GC-FID 6890, but I'm having discrepancies between two standards. The standard that I will be calibrating with (Restek's Residual Solvents #1 34105) is 3000ug/mL in N,N-Dimethylacetamide. I'm verifying the…
