It is only possible to subtract a background spectrum from a TIC in MSD ChemStation (File > Subtract Background (BSB) ), not an entire blank run's chromatogram. If this is data being collected by a 2D GC detector (FID, ECD, etc...) then you can use the…
Hi All, We are experiencing a very strange issue (very broad peak) with Dimethyl Formamide Solvent when run with one particular residual solvent method utilizing Dimethyl Formamide as Diluent. Method has been run for the past 4/5 years without any issues…
Hi everyone, A few weeks ago in our lab we installed a new inlet/column/detector set-up on an existing 7890B GC in our lab. This GC already had a front inlet/detector installed and there was never anything installed on the back components. Therefore we…
I have been using Chemstation with my Agilent 7890/5975C for a few years now. I closed down the software and machine to perform a source cleaning.
Now, when I attempt to open Chemstation it state: "GC error: CreateNotificationHost() in InitializeDevice…
We recently purchased a GS Oxyplot column based on its reported excellence for separating oxygenated compounds in hydrocarbons streams such as Ethylene, which is required to be of ultra high purity for polymerization catalysts. Unfortunately we see a…
