Trapping & Desorption

Trapping and desorption are techniques used to collect and concentrate trace gases from air samples for precise chemical identification. Air is passed through a cartridge that captures volatile compounds; gentle heating then releases (desorbs) them into an analytical system such as GC or GC/MS. This method is crucial for environmental monitoring, workplace safety, and emission control, where even tiny concentrations matter. It enables professionals to detect and quantify pollutants accurately, supporting cleaner air and safer working environments.
