Two instruments are running off the one computer (two cards). One is a 6890N/5973N, one is 6890N/5975 with Gerstel Rail. Neither instrument has an FID, just the one MS detector, so only one signal from each. It doesn't seem to matter if both instruments…
Hello,
Having sorted out our printer problem with MassHunter for GC we started having another issue on Friday night last week. The software suddenly stopped mid run giving an error that the drivers for the MSD could not be found. After restarting…
Thanks for advising, do other errors show up in the logbook?
Please watch the movement of the sampler arm during initialisation:
- Is it shaky or jittery? If yes, turn off module and clean transport rods using IPA & lint free cloth.
- Which position…
Hi. The pump made loud noises for several days. After that, the pump stopped working normally. Near 600 rpm the pump stops and A-PLUS Software was showing fail status (205) with error code 206 (bit 128) - too hight load. We use Agilent pump - TPS compact…
Let me summarize...
Everything that you 've shared with us ALAZ looks perfectly normal, except the calibration on one of the FID channels doesn't show all of the calibration levels.
I'm now completely out of ideas. You've done everything that I would…
Hi,
Recently Run the Wavelength accuracy and signal to noise at FLD detector for qualification purposes but it not passing. In wavelength accuracy test got Excitation value 350 it ok but in case of emission got 393 nm its failed required minimum 394…
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…
Hello, I have an issue when I try to install OpenLab CDS EZChrom Version A.04.07 The plan is to install EZChrom on a Citrix to allow the user to retrieve files from ECM for review or reintegration. I start the installation and select the Installation…
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.
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…
