Hello Paul, it looks to me that there is too much acetylene in the gas mixture coming to the burner. This is causing the carbon build-up.
I'd suggest you first remove the absorption cell from the holder and clean this by soaking in dilute nitric acid…
Hello mkaadan ,
What I meant by a "low" failure rate (notice the quotation marks), is that it is likely not an indication of a leak, as that would result in a lot more samples failing, or potentially all of them. By no means I wanted to minimize the…
Can SimDis data processing be performed manually (i.e. without the aid of additional SimDis software produced by Agilent or a third-party) with a GC running Chemstation?
I'm looking for a low-cost solution to perform SimDis analysis of jet-fuel samples…
Hi, I have a GC/MS (8890 GC with 5977b HES MSD) that is also configured with an FID and PDHID. I would like to create an FID/PDHID-only method, where the MSD remains off the entire run and does not collect data. I haven't figured out how to do this so…
l have lc 1260 pump type G1311c and it is in residual mode due to installing a degasser board on the pump board. I used the Lab Advisor program to update the firmware, but the process was not successful and messages appeared. Connection failed instrument…
Hi everyone. I have a problem with my 8890 GC-MS as I do not have pressure in the inlet. The issue began during the IT outage, the EPC module turned off itself hence all heated zones turned off as well. When I managed to re-establish the connection I…
Hi ISH, yes all was fine with column installation and pump down was efficient. The issue seems to be with the entrance lense offset - I loaded a previous tune and managed to run an autotune however it is failing due to too high 503/502 ratio. I've seen…
HI Lars,
Yes, you can run the test on a VI. Specific to your system, a failing result could indicate a leak within the inlet or at any of the in-line connections of your GSV, so the results may not be clear without a point leak detector. I would also…
Hello, H2 is the fuel for the flame in the FID, so if you are out of H2 then the FID will not be able to light. That is very likely the reason why you are not seeing a signal from the FID.
