Hi everyone,
We have detected fails in 3 FLD modules installed in the same instrument.
The fist of these gave the error 06712 (emission motor did not find position),and was replaced with a second module. This when it was being installed failed again…
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…
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…
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…
Hi All,
For the last 1.5 years, the pump has been running fine even though the rear seal wash was blocked. Then in September, we were having issues with our pumps and found there was leaking in pump B. We did a maintenance, meaning cleaning the pumps…
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…
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…
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,
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…
I have configured my laptop to our 8890 GC with a split/splitless inlet and FID. I am currently just doing manual injection. When sending the method from my laptop to the instrument, all of the parameters reach the setpoints except for my column temperature…
