When running a calibration on the GCMS the internal standard increases the entire time for all of our standards. It goes from around 1.9 million for the bottom of the calibration to 3.2 million. Recent things that we have done that should help eliminate…
Hello, we were not able to tune the instrument at all. There was so much noise at low mass that it fails the initial quad coarse mass calibration. We think it is PEG contamination, possibly also PPG, but a number of masses correspond with sodiated PEG…
The tune evaluation criteria are benchmarks that GCMS instruments typically pass.
"Designed for" and "works with" are two different things. The tune evaluation was created before the Extractor Source and High Efficiency Source. These ion sources get…
Hey Ryan, try the following. Normally, the valve command failed is coming as a result of the position not found. Overtightened screws are a typical result if you have done maintenance before (happened to me the first time...). Tighten the screws each…
Morning, You are correct. I am running OpenLab CDS ChemStation. Rev code = C.01.04 [35]. Intelligent Reporting product version A.01.04.122. The system suitability issue is that I'm only getting the TCD satistical results. The FID result are not printing…
Hello Lars, Thanks for your reply. Unfortunately, there is no flow meter meter installed. So you are saying that, in your case without stopping gas flow before GC injection, you are only getting 1-2% deviation in FID response? If possible could you explain…
I have a G4226A autosampler with a recurring error message. Movement of needle into seat failed [EE 4714, 3204]
This error started after the autosampler had been repaired by a field engineer. The main board had to be replaced; the computer was unable…
I think that, with this version of the software, there are configuration files stored in the "instrument number folder", e.g. C:\Chem32\n I was going to suggest that you try to delete/rename the config.reg file, having closed all instances of Chemstation…
