Solid-phase microextraction: a powerful sample preparation tool prior to mass spectrometric analysis Gyorgy Vas¨ 1∗ and Karoly V´ ekey´ 2 1 Department of Biomedical Mass Spectrometry, University of Antwerp, Universiteitsplein 1, B-2610 Wilrijk, Belgium 2 Chemical Research Center for Chemistry of the Hungarian Academy of Sciences, Pusztaszeri u. A novel approach is described for the quantitative bioanalysis of drugs in blood samples by ionization of the analytes collected on solid-phase microextraction (SPME) fibers by mass spectrometry (MS). The technique combines the attractive features of SPME microsampling using minimal sample volumes with the speed, selectivity, and sensitivity capabilities of MS detection. 2 It is a solvent-free sample preparation technique that integrates sampling, isolation and concentration.

SPME had sufficient sorptive capacity to permit detection of aroma compounds having a variety of functional groups. Its advantages are miniaturization; considerable reduction or even complete elimination of the use of toxic sol vents; high concentration factors; low cost; SPME uses a fiber coated with a liquid (polymer), a solid (sorbent), or a combination of both.

The fiber coating extracts the compounds from your sample by absorption in the case of liquid coatings or absorption in the case of solid coatings.
