We know perfectly well that a cleaner sample yields better result. Several main parameters, including the amount of the sorbent, extraction time, ionic strength and desorption conditions, were independently optimized and the results were compared to find the best extraction setup for dispersive micro-solid phase extraction. Food Additives & Contaminants: Part A Volume 33, 2016 - Issue 2.

Solid-phase microextraction (SPME) is a simple, sensitive, rapid and solvent-free technique for the extraction of analytes from gaseous, liquid and solid samples and takes a leading position among microextraction methods. SPE is a sample preparation technology that uses solid particle, chromatographic packing material, usually contained in a cartridge type device, to chemically separate the different components of a sample. human urine using micro-elution solid phase extraction Key words SPE, SOLA, SOLAμ, SCX, Hypersil GOLD aQ, opiates Goal To describe a reproducible optimization procedure for the isolation of opioids from human urine utilizing solid phase extraction (SPE). Micro-solid phase extraction with liquid chromatography-tandem mass spectrometry for the determination of aflatoxins in coffee and malt beverage. Solid Phase Micro Extraction is to be used as the main extraction technique and detection using several gas chromatography. Solid-phase microextraction (SPME) is a simple, sensitive, rapid and solvent-free technique for the extraction of analytes from gaseous, liquid and solid samples and takes a leading position among microextraction methods.
