Laboratory, industrial, chemical, or other waste products may have constituents that evolve volatile organic compounds (VOCs) at very high concentrations. The paper presents an inlet system and analytical method for gas chromatography - mass spectrometry designed specifically for measuring VOC concentrations greater than 10 parts per million by volume in a gas matrix. The technique is shown to be effective for measuring selected common solvents including alcohols, ketones, halogenated hydrocarbons, and aromatic compounds in an air matrix in stainless steel sampling canisters.
