Solid phase microextraction, or SPME, is a solid phase extraction sampling technique that involves the use of a fiber coated with an extracting phase, that can be a liquid (polymer) or a solid (sorbent), [1] which extracts different kinds of analytes (including both volatile and non-volatile) from different kinds of media, that can be in liquid ...

Solid phase microextraction (SPME) is a solvent-free sample preparation technology. Based on the principle of adsorption or absorption and desorption, SPME uses a coated fiber or Arrow to concentrate volatile and semivolatile compounds from a sample.

2023年7月12日 · Solid phase micro-extraction, is a solvent less sample preparation technique introduced by Belardi en Pawliszyn in 1989 [1]. In SPME, an easy-to-use device containing a coated fiber to concentrate volatile and semi-volatile organics extracts target analytes from the matrix in one step. SPME consists of two processes:

Solid phase microextraction (SPME) is a non-exhaustive sample preparation technique in which a small volume of extractive phase (immobilized on a solid support) is exposed to the sample for a well-defined period of time. You might find these chapters and articles relevant to this topic. M.W.J. van Hout, ...

Solid Phase Microextraction (SPME) is a fast, solvent-less sample extraction technique. It is used for extracting organics from a matrix (solid, liquid, or gaseous) into or onto a stationary phase immobilized on a fiber.

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.

2022年8月1日 · Solid-phase microextraction (SPME) has become a powerful sample preparation technique which allows to efficiently isolate and enrich analytes from complex matrixes. One of the most widespread SPME modes, consists of the extraction directly from the headspace (HS) which is equilibrated with the sample.

Among other modern sample preparation techniques, solid-phase microextraction (SPME) is a state-of-the-art, solvent-free technology that was developed by the research group of Pawliszyn [1] in 1989.

SPME is a reusable, inexpensive method for sample preparation, requiring an SPME fiber assembly and holder for diverse sample analysis.

Solid Phase Microextraction (SPME) is an extraction process for both volatile and semi volatile compounds in preparation for GC or HPLC analysis. One of the major benefits of SPME is that by choosing the proper extracting phase coated on a SPME fiber, target analytes can be extracted leaving unwanted compounds behind in the matrix.
