Abstract

Temp. programmable (PTV) injectors with packed wide-bore (.apprx.3.5 mm inside diam.) liners are used for large vol. injection in capillary gas chromatog. to simplify and/or improve off-line sample pretreatment procedures. A simple procedure to optimize large vol. PTV injection is described. System performance, i.e., linearity and repeatability, was evaluated for polar N/P contg. pesticides (PTV-GC-NPD) and organochlorine pesticides (PTV-GC-ECD) in river water exts. and for polycyclic arom. hydrocarbons (PAH) in river sediment (PTV-GC-MS).
