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…
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…
Hello,
I am getting the following error on OpenLab CDS Chemstation Edition (Rev. C01.10 [287]): "User Change (Unlock) failed, because instrument access is not permitted for user. Logging Out User". We are initially able to login once, but then when…
Hello mdeighan ,
Manual integration is limited to the rules of the selected integrator and the settings of your quant method. The error and behavior you are seeing typically indicate that the peak you are attempting to create is too far outside of the…
The mass calibration/check for the quadrupole is failing across all isolation widths. Mass delta on 322m/z exceeds limits.
We system tuned a few weeks ago. Can someone please outline the troubleshooting workflow for this type of issue (where to start…
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:

Hello, Our lab has a GC-MS (7890B/5977B) system which uses MassHunter version B.07.01 SP1. We recently installed a FID on the system to run FID analysis separate from the MS. We are finding that MassHunter is not as suitable to use for FID analysis in…
I am currently having a flow issue with my 6890N GC(w/ G1888 HS). I am doing yearly flow checks. Hooked up a calibrated flow meter to DET exhaust and turned off all gases (pressure off, makeup He off, Air off everything). I then enabled them one at a…
