Applying Agilent's unique technology, the Agilent Dual Shot EGA GC/MS system can change the inlet line and maintain the injection port without MS vacuuming, so as to realize high-efficiency, accurate and automatic analysis.
The document describes an application using a Frontier Laboratories Double Shot Pyrolyzer coupled with an Agilent GC/MS system. It details how Capillary Flow Technology enables column switching between Gas Evolution Analysis (EGA) and Double Shot Analysis without venting the MS, preventing air ingress and maintaining vacuum integrity.
Additionally, the note explains the utility of backflushing to remove high-boiling components from the inlet liner after analysis. This process shortens cycle time, reduces detector contamination, and extends column life by lowering the temperature before the next run. This manual is written in Japanese.
It allows for the exchange of columns between Gas Evolution Analysis (EGA) and Double Shot Analysis without venting the mass spectrometer.
Backflushing removes unnecessary high-boiling components, reducing analysis time by 21.3 minutes and preventing detector contamination.
