Evaluation of the Basic GC/MS (Gas Chromatographic/Mass Spectrometric) Computer Analysis Technique for Pollutant Analysis

摘要

The basic gas chromatographic/mass spectrometric/computer technique for the analysis of vapor-phase organic compounds collected on a solid sorbent was evaluated. Emphasis was placed on the assessment of performance and improvement in techniques in the following areas: (1) wide-bore wall coated columns for organic vapor-phase analysis; (2) gas chromatography/negative chemical ionization mass spectrometry/computer analysis of halogenated/hydrocarbons in ambient air; (3) the concentration of vapor-phase organics from the atmosphere on solid sorbents (in situ reactions); and (4) qualitative and quantitative analysis of vapor-phase organics utilizing the improved technology.
