The Progress of Sample Preparation and Treatment Solvent-Free Extraction Technologies

Solvent free extraction as a promising technique for sample preparation and pretreatment which has become one of the most important research areas in modern analytical chemistry has attracted much attention recently. The basic principles and applications of the methods, such as gas phase extraction, supercritical fluid extraction, membrane extraction, solid phase extraction, and solid phase microextraction were described in this paper. The trends in the development of these methods were also discussed.
