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…
Hi wcody, thank you for the reply! It is Windows 10 Pro 64-bit. These 6890 FIDs are new to the lab, Windows 10 pro was what the technicians had installed on the computers when we received them.
James, Thanks again. Actually, at first we had "EPC or detector error” and we tried to clean the detector but with no change. Once the GC says “Ignite, ignite” the error pops out. We tried second module (the refurbished) and at first we were receiving…
There is currently no available solution for working with MassHunter data. If your GC has an FID in addition to a mass spec, you could use OpenLab GC ChemStation to acquire the FID signal data. Then addon G2887BA could be used to analyze the ChemStation…
Hello,
We just recently got a new tapestation 4150 in our lab, which we're trying to set up. As a part of the setup I rand the full system diagnostics to see if the system is working with the Tapestation Test Tape. Everything runs successfully and the…
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…
ISH, that is a very good question. Yes, you can. However, you have to be mindful of a few things. For the Deans Switch to operate optimally, the downstream pressure need to be the same on both columns downstream of the Deans switch. The MSD operates under…
