ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of methyl chloride. It presents detailed information on the air analysis and analysis of aqueous and nonaqueous samples of methyl chloride. Methyl chloride is colorless gas with a faint sweet odor. It is slightly soluble in water and miscible with organic solvents. During the analysis of aqueous and nonaqueous samples of methyl chloride, aqueous samples are subjected to the purge and trap extraction method. The aqueous extract or a solution of methanol extract is spiked into water. During the air analysis of the methyl chloride, samples are collected in a SUMMA passivated canister under pressure using an additional pump or at subatmospheric pressure by initially evacuating the canister. Then, the air is transferred into a cryogenically cooled trap attached to a gas chromatography (GC) column.
