Hi Jennifer We had an GC-MS issue in the past where the rough pump was starting to fail and as a result kept drawing too much current, causing some of the fuses to fail. We also had an issue with a rough pump (on a LC-MS) which was blowing fuses when…
Hi ronin, It sounds like you have a 7694A with the newer headspace mainboard (7694B) that didn't have the visible changeable battery. In this case the ability of the board to retain stored parameters has failed due to this battery failing. The only fix…
Hi all We are using GC6890N in our lab to analyze dry gas, the GC with TCD and FID and four columns Two weeks ago We noticed something strange in the results like a cycle. N2 value it goes up and then goes back down. Is there any advice to solve this…
Hello everyone!
Which one do you prefer in 2019, Openlab CDS Chemstation edition or Openlab CDS-2 and why, some standard list of pros and cons maybe?
The 7890B instrument has 2 FIDs, two capillary columns in the same oven, each column connected to…
Hi,
I'm having some persistent calibration issues for an ICP-OES analyzing Al, Ca, Fe, K, Na, Ni, P, Si, V & Zn in the range of 0.05 - 1 ug/mL.
The following lines (Al 237.312, Si 185.005 and Na 589.592 nm) keep failing the calibrations due to lowered…
I have seen cases where the rough pump shuts down because it's working too hard, which will cause the MSD to shut down also. Typically the MSD will have an error message of "Vac Sys Fail" or something similar.
Can anyone explain the negative dips in the MS TIC and why they are perfectly aligned with the spikes in the FID? Is there any troubleshooting that I can do to relieve this problem? thank you

After servicing pump, test still fails. We are using n-heptane as solvent/carrier, is correct to use n-heptane for the pressure/leak test? Or, do we need to do it with isopropanol?
Sounds good. Just wanted to double check why it was not working. I had a noise and drift test fail before on LabAdvisor and it was due to a test not functioning properly. The Leak test and Pressure test both passed and system has been working fine. Thanks…
