The 'batch process', analogous to liquid-liquid extraction, involves grinding the solid to a fine powder, mixing it with the appropriate solvent, and filtering off the solid by gravity or under vacuum and then evaporating the solvent from the extract solution. Steroid Solid Extraction Protocol For our DetectX® Steroid Immunoassay Kits SAMPLE ANALYTE CONCENTRATION CALCULATION: Assay Concentration (i.e. pg/mL) x Assay Dilution Factor x Reconstitution Vol (mL) ÷ Evaporation Vol (mL) ÷ 0.1g fecal solid/mL = Analyte unit (i.e., pg/gm) fecal solid. Example of extraction scenario and subsequent calculations. Solid Phase Extraction Products Thermo Scientific™ HyperSep™ Universal Vacuum Manifold Use this flexible vacuum manifold to process samples using both solid phase extraction … Not familiar with solid-phase extraction? Not to worry.
SPME has been Solid/Liquid extraction process is a very common process in the pharmaceutical, cosmetic and food industry to obtain natural ingredients as e.g. flavors and fragrances from natural raw material. The extraction can be carried out with cold or hot solvents. Other solid-phase extraction media may be employed as described in Sec. 6.0.

Information and translations of solid phase extraction in the most comprehensive dictionary definitions resource on the web. Classically, the extraction step has been accomplished using liquid-liquid techniques, but in recent years, the use of solid phase chromatographic techniques has become increasingly popular. Numerous companies now market solid phase columns that are designed specifically for extraction of drugs, some of them containing as many as three different components for extracting acidic, basic, and Solid – liquid extraction 8.7.1.

Theoretical background Solid – liquid extraction (or leaching) is the separation of a solid solute from a mixture of solids by dissolving it in a liquid phase.

Solid phase extraction 1 (SPE) is a sample preparation technique using a solid adsorbent contained most commonly in a cartridge device (Figure 1), or on a disk to adsorb select species from solution. SPE is used to isolate a species in a sample or to clean-up a sample before analysis. Solid phase extraction is a method that has both a mobile and a stationary phase. These two phases work in conjunction to extract the compounds you’re looking for. The stationary phase and mobile phase will vary drastically depending on the results you are trying to achieve.
