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…
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…
Hello,
We have been having issues with our ICP MS performance and tune reports. Both have been failing with low counts. We have changed the peri-pump tubing, remade all standards, remade the tune solution, replaced the torch, and cleaned the cones…
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…
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 Everyone, I am hoping I could get some advice with separating Aniline and DMSO with GC-FID.
We tried DB-Wax, DB-624, DB-5 so far but it did not work well. The retention time could be 2 min different max but the problem is DMSO has some impurities…
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…
Hi I had a question about GC MS Split (gc to FID/MS). I have a thermo splitter that has no auxillary flow to counteract the ms vaccuum, but want to change out the capillaries that come recommended with the splitter. The recommended capillary dimensions…
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 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…
