Hi there! We have a Cary 60. We are doing preventive maintenance, but the noise test fails and it took up to three or four times to get a successful result. What can we do to improve this and get a passed result the first time?
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…
Hi I have a very basic question, please correct me if I am wrong. I am using GC 7820 with FID detector. Flow , Pressure everything was set by another technician before I started. I know for Back Detector everything is what is set by the Technician in…
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…
Hi,
Our QTOF system failed to do a polarity switch from positive to negative. But it works fine at the positive mode. Just wondering if anybody knows the problem. Here is the instrument log record:

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…
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…
