Non-porous membrane extractions in contemporary analysis

Sammanfattning: To meet the desirable characteristic for sample preparation in contemporary, i. e. automation, high enrichment, clean-up, selectivity and essential solvent free techniques, the use of non-porous membrane extraction techniques is addressed. Principles, practices and province of the techniques are described as well as hyphenation with separation techniques. Furthermore, works in the thesis covers methods applied to both environmental and biological sample for the extraction of compounds ranging from organic acids and bases, metabolites to cationic surfactants. The methods presented in the works meets the desirable properties regarding automation, high enrichment, clean-up and solvent consumption.
