Hi abtisam, The main reason for this problem you didn't select detector signals. when we don't selecAdd t signal detector we never see baseline chromatogram,to solve this problem from online plot for FID signal Click on change than from Edit signal plot…
The GC Calculators and Method Translation Software (MTS) is available for download from Agilent.com . The package includes:
The Vapor Volume Calculator . It can be used to determine the expansion volume of a GC sample solvent at a given inlet temperature…
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…
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…
Dear Team,
Is it OK to use 8860 system for USP467, residual solvents analysis ? Literature that is available is mainly on 8890 but 8860 can also be used ? Agilent do have a blood alcohol analysis app note on 8860 with HS, 1 SSL, a Tee connection, 2…
What are the pros and cons of putting a TCD in series with an MS? I know that it's possible to put a TCD and FID in series but I want MS data, not FID data. I tried teeing off the column between the MS and TCD but all the samples keep going to the MS…
I'm doing Injection Sensitivity test for GC using FID Performance Evaluation Sample Kit. I'm not using an Integrator, I'm using ChemStation. I know that the typical amount obtained using ChemStation is around 4000 pA*s. What would be the specification…
Hello, In my 6890 GC-FID appears the status message: Back det H2 flow . It is a random message and when it appears I have a lot of noise in my chromatogram I have cleaned the detector, the jet and reinstalled the column but the problem appears again.…
Hydrogen (H2) is the simplest and most abundant element in the universe. Since, it only occurs naturally on Earth when combined with other elements it must be produced from other sources. It can be produced without a carbon footprint from variety of sources…
