Membrane-Assisted Solvent Extraction of Triazines and other Semi-volatile Contaminants directly coupled to Large-Volume Injection/Gas Chromatography-Mass Selective Detection

A simple device was developed for in-vial liquid-liquid extraction with a polymer membrane (nonporous polypropylene) separating the aqueous sample from the organic extractant. The membrane consisted of a tubi ...
