Extraction techniques based on solid state and connected with liquid chromatography

ABSTRACTExtraction methods applied in analysis of water samples can be named as liquid chromatography. Very often, these techniques are used as sample preparation method before another analytical method such gas chromatography or high performance liquid chromatography. The subject of this review is to compare the extraction techniques of liquid samples and discuss their characteristics in comparison with liquid chromatography. Some new extraction techniques are described, and some characteristic parameters are compared.
