I am using Agilent 8890. I am trying to set the standard for my GC-FID, I am injecting 5mL of methane gas standard with a gas-tight syringe through a switching valve which is set up to the left of my GC. However, I am getting different peaks and areas…
Hello pchinolla ,
If you are referring to B.08.00 Qual Navigator then I'm not able to find a way to label the TIC peaks with the associated compound information. You can export the Compound table from the Workflows view, but that would not contain the…
Do you know about the maelstrom of molecules, atoms, ions, and electrons that are going on inside a GC/MS Electron Ionization ion source?
The molecules streaming out of the end of the column in molecular flow come out at approximately the speed of sound…

Hi Fury,
Are you using Cary WinUV with the CFR Package which uses CRM? There should be someone who has qualified your system and would also have access. You can also, reinstall the software since there isn't that much to the initial setup if you haven…
Locking does not appear to be designed to lock specific methods as it is to lock the app to prevent say Scan or Kinetics to be used by a second account while the first person is using it.
