Pesticides, widely applied in agriculture, can produce a variety of transformation products and their continuous use causes deleterious effects to ecosystem. Efficient and sensitive analytical techniques for enrichment and analysis of pesticides samples are highly required. Compared with other extraction methods, solid-phase micro extraction is a solvent free, cost effective, robust, versatile, and high throughput sample preparation technique, especially for the analysis of pesticides from complicated matrices. Coupling of solid-phase micro extraction with gas chromatography and mass spectrometry and liquid chromatography-mass spectrometry has been extensively applied in pesticide analysis. On the other hand, in recent years, combination of fast separation using solid-phase micro extraction and rapid detection using ambient mass spectrometry is providing highly efficient pesticide screening. This article summarizes the applications of solid-phase micro extraction coupled to mass spectrometry for pesticides analysis.
