Than you should probably stop advertise it as a sulfur-specific filter on specs table (add "and hydrocarbons" words) https://www.agilent.com/en/products/lab-supplies/chromatography-spectroscopy/gas-management/gas-clean-purification-syste… . Otherwise…
Autostart Macro failed, error# 999 occurred (OpenLAB CDS Chemstation Rev. C.0x.0x) This is usually resolved by resetting the instrument configuration files in the instrument folder (\Chem32\x\, where x is the number of the instrument in question). Append…
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…
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…
Hi evryone
Please help: i just get these 2 messages which make me i can not inject from my 7890A and 5973C MSD " tune action stopped: cannot achieve constant peaks widths " also "limits fail: pump oils (days), tune time (hours) at the same moment the…
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 don't know if this applies to your specific problem, but a lot of failed uploads and other problems can arise because the GCMS users don't have the proper privileges in ECM. Below is an image with the proper privileges. Assigning the ECM Contributor…
