Solid Phase Extraction Guide | Thermo Fisher Scientific - US
Solid phase extraction (SPE) is a sample preparation technique often used by chromatographers prior to analysis. SPE is most often used to remove interfering compounds from a sample, although it can also be used to enrich/concentrate analytes of interest in the sample.

Critical materials (CMs) are a group of elements that have been determined to be important for the modern economy, but which may face current or
EPA 1664A; Oil and Grease by Solid Phase Extraction (SPE)
Introduction EPA 1664A refers to the Solid Phase Extraction (SPE) protocol for extracting hexane extractable oil and grease materials from water samples. The method calls for the passage of a 1 liter aqueous sample across an SPE cart-ridge or disk, then eluting the cartridge or disk with n-hexane.
A perspective on developing solid-phase extraction
Solid-phase extraction offers numerous advantages for critical materials recovery, and research in the field would benefit from increased focus on environmental impact, techno
Solid-phase extraction for oil and grease analysis - ResearchGate
Solid-phase extraction techniques were applied to the determination of oil and grease. Compared to conventional analysis, SPE reduced solvent use, reproducibil ity was increased, and higher

2. Solid-phase extraction Solid-phase extraction (SPE) is one promising hydrometallurgi-cal method for which numerous experimental techniques have recently been proposed.
A perspective on developing solid-phase extraction
Solid-phase extraction (SPE) is one broad category of these experimental extraction technologies.SPE involves the application of a solid material to preferentially retain in the solid phase one or morespeci铿乧 components of an aqueous solution, leaving the other components behind in the aqueousphase.

Purpose: Column conditioning prepares the sorbent for effective interaction(s) with the compounds of interest. 1. An appropriate solvent conditions the column and activates the ligands on the chromatographic surface 2. The solvent should have similar characteristics (solvent strength, pH, etc.) to the sample to ensure maximResearchGate
Quantitative determination of oil films/slicks from water
The oil/CytoSol mixture spread rapidly to form a uniform layer over the whole water surface of the beakers. Sampling of the water surface (Figure 1) involved placing a C-18 solid-phase extraction disk (SPE Empore? Filtration Products, St. Paul, MN) on a fritted funnel that was attached to a small pump. A slight vacuum was applied to hold the
