A new sensitive, selective, fast and accurate technique for online sample preparation was developed. Microextraction in a packed syringe (MEPS) is a new miniaturised, solid-phase extraction (SPE) technique that can be connected online to GC or LC without any modifications. In MEPS approximately 1mg of the solid packing material is inserted into a syringe (100-250 ml) as a plug. Sample preparati...

A device and a method for sample preparation have been developed, which make it possible to implement successive stages of thermal separation volatile components from solid (liquid) matrix, their capture the gas phase by sorbent, liquid microextraction sorbates further chromatographic analysis. The algorithm its application GC–MS determination number organic compounds matrices with complex chem...
