Study of New Technology on Solid Phase Extraction

As an important pre-treatment mean for extraction, separation, purification and concentration, the method of solid phase extraction (SPE) has gained extensive attentions recently. Due to the popularity of SPE, many new technologies appeared could combine with SPE in order to improve the selectivity, trace enrichment, mechanization and environment-friendship. In this paper, many developed SPE methods were introduced on extraction principle, innovation, restriction and commercialization.
