Sinossi
New regulatory restrictions on using solvents have led to an increased emphasis on developing solvent-free sample preparations. New and established solvent-free techniques that use gas, membrane or sorbent extracting phases are being investigated for various applications, and the need to optimize these new methods has sparked research into fundamental extraction processes. This monograph describes one of the recently developed solvent-free sampling/sample preparation techniques, solid phase microextraction (SPME).
