microextraction SPME offers rapid sample preparation both in the laboratory and field 1 The basic concept of the technology is a sorbentcoated rod that is put into contact with a sample gaseous liquid semisolid or the headspace of liquids or solids The sorbent is selected to have good affinity for the analyte of interest In SPME analytes establish equilibria among the sample matrix the headspace above the sample and the polymercoated fused phase There are two categories of SPME extractions headspace most common and direct immersion DI where the SPME fiber or Arrow is immersed into the aqueous
