ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of vinyl chloride. It presents detailed information on the air analysis and analysis of aqueous samples of vinyl chloride. Vinyl chloride is used as a monomer to make PVC resins and plastics. It is a colorless gas, slightly soluble in water and miscible in organic solvents. During the analysis of aqueous samples of vinyl chloride, aqueous samples are extracted by the purge and trap method. The analyte is thermally desorbed and swept onto a gas chromatography (GC) column for separation, and detected by hall electrolytic conductivity detector (HECD), electron capture detector (ECD), and MSD. During the air analysis of vinyl chloride, samples are collected in a SUMMA passivated canister under pressure using an additional pump or at subatmospheric pressure by initially evacuating the canister.
