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…
Hi there, I noticed recently that the ECD back signal on Agilent GC 7890 (using it for trace gas analysis) is oddly spiking (while the FID is a straight, consistent line). It never used to do this. I just recently changed the inlet septum, could this…
Hi Crystalnipp (great username!!) Thanks for the clear answer I do have a question for you. We also run N2 make-up to our FID. As of now we run He and our night standby method is to leave the GC oven at 150°C with 0.5mL/mim He flow. We turn flame and…
Hello community, I set up an Agilent 6890 (Software: ChemStation A08.03). A few seconds after I start the GC, the error message "Shutdown ( # 6 ): Back Inlet Flow Shutdown" is shown on the display. The settings of the Back Inlet shows that the pressure…
Hi, I am using a 6890 GC in split mode with an isothermal temperature and no flow ramp and operating in constant pressure mode. Please can you advise how using the setting constant makeup flow for the FID detector is different to constant column and makeup…
Hi I use a custom software to control GC6890/FID parsing command through RS-232 connection; I 've only a limited set of commands to control the gc parameters (i.e. zone temp, pressure, FID gas flow ) and I would like all the set of command available in…
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,
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…
Hi a.fedulova, I asked one of my Varian colleagues your question and he provided the below answer. Remove all dashes and leading zeros from Varian part numbers: 15-003347-00 becomes 1500334700, replaced by 1500334701 - 25pack of FID crunch washers [available…
