Palavras-chave: Internally cooled solid phase microextraction, chromatography, sample preparation techniques.

Resumo: Solid phase microextraction (SPME) is one of the modern sample preparation techniques which is deeply changing the separation sciences. This technique is very useful for determination of analytes present in low concentration even from complex samples, and become the analytes detectable by methods such as high-performance liquid chromatography, gas chromatography and capillary electrophoresis. This paper aims to discuss the fundamental aspects and some applications of a new SPME generation which is internally cooled, avoiding the SPME exothermic effect.
