This application note describes the GC/MS analysis of humidified canister air toxics samples at various relative humidities, using cryogen-free systems for thermal desorption preconcentration. Detection of 65 target compounds ranging in volatility from propene to naphthalene is demonstrated with excellent peak shape and performance well within the criteria set in US EPA Method TO-15, including method detection limits as low as 4 pptv.
