WebSolid-phase microextraction (SPME) is a solvent-free sample preparation technique that integrates sampling, isolation, and concentration. From: Handbook of Solid Phase … Solid phase microextraction (SPME) is an innovative and sensitive solvent-free sample preparation technology. Based on the principle of adsorption/absorption and desorption, SPME uses a coated fiber to concentrate volatile and semi-volatile compounds from a sample. See more SPME uses a fiber coated with an extraction phase: a liquid (polymer), a solid (sorbent), or a combination of both. The coated fiber is housed in a protective needle and attached to a holder that looks like a syringe. When … See more Conventional SPME is used to extract and concentrate analytes for the purpose of GC analysis. Extraction is carried out either by direct immersion (DI-SPME), where the fiber is directly immersed in the liquid sample, or … See more SPME combines analyte sampling, isolation, and enrichment into one, simple step. By controlling the polarity and thickness of the fiber coating, maintaining consistent sampling time, and controlling several other … See more Supel™ BioSPME is a bioanalytical microsampling and sample preparation technique used to quickly and selectively extract a broad range of analytes from biological samples while repelling unwanted … See more

WebMar 28, 2003 · Abstract. The solid-phase microextraction (SPME) device was used as a time-weighted average (TWA) sampler for ethylene oxide. Carboxen/polydimethylsiloxane (CAR/PDMS) fiber was used and hydrogen bromide (HBr) was loaded onto the fiber. The SPME fiber assembly was then inserted into PTFE tubing to improve the wearer's … WebPublisher Summary. Solid-phase microextraction (SPME) is a solvent-free sample preparation technique that integrates sampling, isolation, and concentration. Its simplicity of use, relatively short sample processing time, and fiber reusability have made SPME an attractive choice for many analytical applications.
