Autor: D. W. Bottrell, H. B. Kerfoot, E. N. Amick, J. D. Petty, S. L. Pierett

Publikováno v: Journal of the Air & Waste Management Association. 40:1106-1113

A field evaluation of the performance of four portable gas chromatographs was conducted at two field sites, one in the Pacific Northwest (chlorinated solvent contamination) and one in the Desert Southwest (primarily jet fuel contamination). The purpo

Gas-Liquid Chromatographic Determination of S,S,S-Tributyl Phosphorotrithioate (DEF) in Water and Fish Tissue

Autor: R H Wiedmeyer, Lawrence M. Smith, R G Lehmann, J D Petty

Publikováno v: Journal of AOAC INTERNATIONAL. 66:673-676

Methods are described for determination of S,S,S-tributylphosphorotrithioate (DEF) at levels as low as 5 parts per billion in fish and 200 parts per trillion in water. Fish tissue extracts are subjected to gel permeation chromatography (GPC) and sili
