Determination of Lead in Blood and Urine by SPME/GC
Analytical Chemistry, 1999Lead is the most frequently quantitated toxic metal in biological matrixes. In this paper, a method is described for lead determination in whole blood and urine using solid-phase microextraction (SPME) gas chromatography. Lead ion is first derivatized with sodium tetraethylborate to form tetraethyllead, which is then extracted from the headspace over ...

SPME-HPLC: A new approach to the analysis of explosives
Journal of Hazardous Materials, 2007Methods developed for the analysis of explosives by SPME coupled to HPLC are reviewed with special emphasis on determination and monitoring in environmental samples such as soil and water. Analysis of explosives by using SPME-HPLC as analytical technique is comparatively a new method on which a special attention is focused nowadays.

Microestrazione in fase solida (SPME)
2014La microestrazione in fase solida (SPME, solid-phase microextraction), sviluppata da Pawliszyn e collaboratori nel 1989 (Arthur, Pawliszyn, 1990), e una tecnica che utilizza una fibra di silice fusa, rivestita esternamente da una piccola quantita di fase stazionaria adsorbente, che viene esposta al campione.
