Membrane methods of substance separation in analytical chemistry

A review of the membrane methods of substance separation used in analytical chemistry is presented. Membrane methods based on gas-diffusion separation and dialysis extraction, membrane filtration, membrane extraction, and chromatomembrane separation are considered. The possibility of combining membrane methods with modern methods of substance determination, such as flow-injection analysis, gas and liquid chromatography, capillary electrophoresis, mass spectrometry, and so on is discussed. The list of references consists of 200 items.
