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 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…
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…
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…
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…
I have a 6490 QQQ. Each time I run either autotune or check tune, I get masses that are out of tolerance especially in MS2. The system seems to pass if the Dynamic Ramp Table enable button is checked. This is associated with the collision cell and detector…
I’m sorry for the delayed reply to your message. Do you still need assistance with this? If you do, please take into consideration the notes below. However, if the issue was resolved, could you please share what the resolution was?
From what I understand…
Based on your latest results, I would say that nothing is fundamentally wrong with the optical unit in terms of noise, so I believe this is more an applicational problem - your passed quick noise test points to that direction. The error 1050 with the…
