Hello All, Not certain if this is the proper location for such a question, so please feel free to indicate the correct location if I am in error. Issue: Difficulty with GC Chromatography and irreproducible injections - Specifically, the chromatography…
Hello, I apologize for the delay. A lot of times, autostart macro failed errors are caused by corrupt instrument config files. Try resetting the instrument configuration files in the instrument folder (\Chem32\x\, where x is the number of the instrument…
So just to let everyone know, the SSD on this computer has now already failed. Seems like there was something wrong with the hardware to start with !. Let's hope a new SSD will fix this issue. -Francois
Hello, Since each compound in your processing method would require a different resolution pass/fail threshold, I do not believe you would be able to set this up solely from the column properties on your intelligent report. I approached this by storing…
Hello, Is there an update available for the Chemspider library editor script? The script is named DownloadMolfilesFromChemspider.libedit and as the name suggests, downloads the mol files for each library entry from chemspider. The chemspider API appears…
The degasser in our G7112B failed (diaphragm in the vacuum pump tore) and I swapped it out with a spare G1311A/G1379 combo while we wait for parts/repair.
Everything is connected and configured properly, the instrument config in OpenLab CDS 2.3 has…
How long is your "electricity problem" ? And what is it? A switchover or a full-on power fail or?
Agilent does not support GC or GCMS on a UPS as too many UPS cannot handle the high amperage load. See: (+) Use of a UPS to Supply Power to an Agilent…
Rapid through-barrier raw material identification
Point. Click. Get a pass or fail result.
It almost seems like magic at first, a workflow so simple it begs the question, why do it any other way? Through-barrier raw material identification is an absolute…
Hello, The tune evaluation on the 5977B GC-MS is failing. The reason is 502/69 mass ratio is smaller than 2.4 (reading = 1.5-2.0), more specifically the 502 m/z count is around 7000-9000, instead of 20000 which is seen in previous autotunes. I cleaned…
Sounds like the Cap EPC module or the EPC Pneumatics board may have failed. Do you have two Cap Inlets? If so. You can swap the two EPC Modules to see if that changes anything. I would lean towards the EPC Module has failed.
