Do you have the Polyboost on? If not, the wavelengths below 190nm will fail. It would be good to know which wavelengths are failing. On the wavecal tab, click "Store dark current" and see where the wavelength calibration file is being saved. Then using…
Hi Lars, I would add an input from my experience that H2 carrier gas may cause some chemical reactions on some specific polar columns and compounds. Two scenarios I have encountered were (1) analysis of C4-C5 olefins on an AL2O3 PLOT column where some…
Hi Azrael, Publication Part Number: A02028 might be one of several apps to look at. if you could elaborate which targets are nice but not required for quantitation? It appears that Argon is the carrier and sample prep diluent gas then, though He/H2 are…
I get a bunch of junk on the front panel of the GC and the detectors I have (PID and FID) end up going cold. It is a bunch of work to re-calibrate due to software stuff we have to do for the method we are running. Plus the 1/2 hr runs I do take a while…
Hello, SW: MassHunter Workstation, Quantitative Analysis, Drug Analysis for GC, Version 10.1 Build 10.1.733.0 I am trying to batch process data acquired by GC-FID but I unable to generate the correct sample result since I don't know where to enter the…
I have been operating an 7890A/5975C with Chemstation version E.02.00.493 for a couple of years. The autosampler is a Gerstel MPS2 (model MXY-02-00B) controlled by Maestro version 1.10[017] and the GC has an FID in the front detector position. I have…
Hello, I have a TCD + FID GC 6890. Need to upgrade to Windows 10, because Windows will no longer provide security updates for Windows 7. Is Chemstation B.04.03 compatible with windows 10? Alternatively, will A.10.02 be compatible with GC6890? Thanks for…
When running hydrogen carrier your source should not need as much physical cleaning (compared to helium carrier) because the H2 has a scrubbing effect. So far I've been told that there is no physical cleaning on the HydroInert source as it could damage…
Hello,
we want to analyse a gas mixture (CO2, CO, propane, ethane and methane in hydrogen) with the HP 6890 Series GC System (G1540A). The gases are coming to the column via a six-way valve and after the column, there is a TCD and a FID detector. In…
