ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of chlorobenzene. It presents detailed information on the air analysis and analysis of aqueous and nonaqueous samples of chlorobenzene. Chlorobenzene is used in heat transfer medium and as a solvent in paint. It is a colorless liquid with a faint almond odor, insoluble in water and miscible with organic solvents. During the analysis of aqueous and nonaqueous samples of chlorobenzene, aqueous samples are extracted by the purge and trap method. The volatile 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), flame ionization detector (FID), or GC/mass spectrometry (GC/MS). During the air analysis of chlorobenzene, samples are collected in a SUMMA passivated canister under pressure using an additional pump or at subatmospheric pressure by initially evacuating the canister.
