Superheated water has been widely utilized in the extraction of organic pollutants, pesticides, natural products as well as inorganic compounds from a variety of sample matrices. The rapid development of superheated water extraction (SWE) has led to the direct combination of this technique with conventional chromatographic methods. However, these coupling methods still required a considerable amount of organic solvent. This book, therefore, introduces a design of an on-line coupled system of SWE method with superheated water chromatography (SWC) by using simple switching valves and a...
