I want to check Total hydrocarbon by FID without identifying the hydrocarbon species . Agilent suggest to give me DB-1 15m, 0.32mm, 0.10u as a non polar column to elute all HC without separation as one peak . Does this column will work for Total hydrocarbon…
We've been having issues with our 7890B gas chromatograph. We have it connected to a workstation running Windows 7 SP1 and OpenLab/Chemstation version C.01.07 [27]. We have a Gerstel MPS attached as a headspace sampler.
We have been trying to run…
Hi silencer2008,
the 1 µL/s rule means the injection speed used for splitless injections, which is very slow compared to split injection where you want to inject as fast as possible.
Two interesting articles would be:
