Solid Phase MicroExtraction - the Leading Sample Preparation method for Complex Samples

May 21 2009

Supelco, a division of Sigma-Aldrich™ (USA) has a unique, patented, sample preparation method, Solid Phase Microextraction (SPME). This innovative, solvent free technology that is fast, economical, and versatile.

SPME is a fiber coated with a liquid (polymer), a solid (sorbent), or a combination of both. The fiber coating removes the compounds from your sample by absorption in the case of liquid coatings or adsorbtion in the case of solid coatings. The SPME fiber is then inserted directly into the Gas Chromatograph for desorption and analysis. SPME has gained wide spread acceptance as the technique of preference for many applications including flavors and fragrances, forensics and toxicology, environmental and biological matrices, and product testing to name a few. By sampling the headspace above a complex sample matrix, SPME helps to minimize effects due to interfering organic compounds.   You can request further information on our range of Solid Phase MicroExtraction sample preparation products or request a copy of the brochure or CD via Email to ukanalytical@sial.com For applications and product selection advice contact our Technical Services Team by Email eurtechesrv@sial.com   SPME is part of Sigma-Aldrich’s innovative and value-driven product ranges that, combined with our services and support, provide complete analytical applications and solutions.
