Volatile Organic Compounds Trapping from Gaseous Samples on the Basis of Co-Liquefaction with Organic Solvent for Gas Chromatographic Analysis

Background: Volatile organic compounds (VOCs) are emitted from a variety of industrial sources and human exhaled breath with endogenous and exogenous origins. For environmental, health, and scientific studies, these compounds must be monitored at trace levels in airborne, gaseous samples and human breath exhales. This article presents the challenges for developing a simple, rapid, non expensive and adsorbent free method for the isolation and enrichment of volatile organic compounds (VOCs) from gaseous samples on the basis of co-liquefaction of analytes and solvent molecules. Keywords: Co-liquefaction, air sampling, exhaled breath, volatile compounds, benzene series compounds, organic solvent.
