Solid-Phase Extraction SPE, sometimes referred to as liquid–solid extraction, is a popular technique for the isolation and separation of analytes from a liquid matrix. Find out more here. Solid Phase Extraction (SPE) is a broad term to describe the digital (step wise) separation technique where liquids contact sorbents, and organic compounds or ions in the liquid adsorb to the functional group (s) of the sorbent. SPE is used to isolate a species in a sample or to clean-up a sample before analysis. QuEChERS salts and SPE sorbents can be purchased in bulk for custom SPE cartridge packing or large-scale purification.

First, the recent developments are given in formats, phases, automation, high throughput purpose and set-up of new types of procedures. SPE columns, packed with small quantities of various chromatographic sorbents, are commercially available.

Products. Every sorbent batch must pass a series of quality control tests to ensure batch-to-batch reproducibility and performance. Solid-phase extraction (SPE) is a sample preparation process that uses solid particle as sorbents, to chemically or physically separate the different components of a liquid or gas sample. Solid-phase extraction (SPE) is a sample preparation method where the compounds that are dissolved or suspended in a liquid mixture are separated from other compounds depending on their physical and chemical properties. Solid Phase Extraction (SPE) Bulk Sorbents & Salts. The objective of this review is to provide updated information about the most important features of the new solid-phase extraction (SPE) materials, their interaction mode and their potential for modern SPE. Bondesil bulk silica, carbon, and polymeric sorbents provide highly selective separation. Skip to main content. A Quick Look at Solid Phase Extraction (SPE) Solid phase extraction is an effective technique for cleaning up and concentrating samples, prior to HPLC or GC analysis. Volkan Numan Bulut, Mehmet Tufekci, Celal Duran, Mustafa Soylak, Halit Kantekin, Selective Solid Phase Extraction for Separation and Preconcentration of Palladium from Gold Ore and Anode Slime after Complexation with a N4O2 Mixed Donor Ligand Derivative, CLEAN – Soil, Air, Water, 10.1002/clen.201000116, 38, 7, (678-683), (2010). Sample Preparation. The technique offers targeted selectivity for analytes of interest, versatility for a wide range of sample volumes, can be easily automated for high-throughput, and is performed by following quick and simple methods ( load, wash, elute) . Solid Phase Extraction (SPE) 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. Home. … Orochem synthesizes a full range of polymer-based, solid phase extraction (SPE) sorbents. Cathinone derivates have become very popular as legal highs and are easily obtained on the market as “bath salts”, getting around the legislation due to their modified structure based on banned substances. If nonpolar, a reversed phase type sorbent will work best. Solid-phase extraction (SPE) is a fundamental technique for the isolation and concentration of analytes from liquid samples or for the clean-up of extracts from a previous treatment. Figure 1. Orochem’s Panthera Deluxe and Agility Deluxe products provide high performance at an affordable price. Sorbents are available in cartridges, 96-well plates, and microelute plate format. For methanol soluble compounds, frequently the reversed phase type sorbents will be effective, but greater selectivity can be obtained with a normal phase type sorbent As with water soluble compounds, the other sorbents are used for matrix-adsorption clean-up methods.

Sorbents are chosen to either retain the components of interest, or selectively release them into a strong liquid phase
