Coupled LC‐GC: A new method for the on‐line analysis of organochlorine pesticide residues in fat

摘要

AbstractThis paper describes the use of coupled LC‐GC for the determination of organochlorine pesticide residues in fat samples. Organochlorine pesticide residues are preseparated from fat by LC on a short C‐18 column using an organic solvent as the mobile phase. Evaporation of the LC eluent is achieved by a modified on‐column interface, introducing an on‐line vaporizer module using the fully concurrent evaporation te
