Gas chromatography coupled to time‐of‐flight mass spectrometry using parallel electron and chemical ionization with permeation tube facilitated reagent ion control for material emission analysis Open
Rationale Volatile organic compounds (VOCs) emitted by an artificial leather part for car interiors are determined using GC–MS (gas chromatograph coupled to a mass spectrometer) using simultaneous electron and chemical ionization (EI&CI). …
