・Direct injection of solvent or gas ・HS (headspace) method Liquid or solid sample is placed in a cial, sealed and heated. Gas phase is collected and injected ・Pyrolysis method Injected after heat extraction or pyrolysis of polymers and high boiling substances ・Heat desorption method
Liquid samples based on Stir Bar Sorptive Extraction (SBSE),
gas concentrated using TENAX sorbent tube, or solid samples are heated
After concentrating the gas phase in the cooling trap, injected by heating and desorbing
Injecting a sample into GC requires not merely introducing a gas or a solvent in which the sample is
dissolved, but also selecting a suitable pretreatment method according to the application
