Simplified gas-chromatographic procedures for the determination of C1—C7 hydrocarbons in urban atmospheres
Abstract
Simple procedures for the determination of C1—C7 hydrocarbons in air are described. Hydrocarbons C2—C7 are collected on a carbon molecular sieve trap and desorbed directly into a porous layer open-tubular column by means of a programmed temperature injector. Methane is determined by direct injection.
