SPE Sorbents Products & Reviews

Evolute WCX is a mixed-mode weak cation exchanger, developed for extraction of strongly basic analytes and quaternary amines from aqueous samples. These analytes are typically found in pesticides and provide analytical scientists with the ability to extract pesticides from diverse matrices ranging from ground water to blood samples.

These cartridges are designed to meet large volume, real world samples. The frits and sorbent bed resist plugging, the format fits several types of manual and automated extraction systems. Various bonded phases available including C18, C8, DVB, & graphitized carbon black.

Robust, Accurate Polymeric Solid Phase Extraction (SPE) Products

Available retention mechanisms include reversed phase, ion exchange, normal phase and mixed mode

Strata-X Drug B and N Solid Phase Extraction (SPE) sorbents are designed and quality control tested for basic and neutral drugs of abuse analysis, respectively. The sorbents are QC tested using drug probes from urine samples so that you can have confidence in your results. The sorbents also do not require conditioning/equilibrating steps, saving both time and solvent.

Bond Elut PRS is a strong cation-exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in nonpolar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, it is recommended for weaker cationic species, such as pyridinium compounds.

Graphitized Non-Porous Carbon  

Bond Elut C18 is the most hydrophobic, bonded silica sorbent available in the Bond Elut range. It is the most popular SPE sorbent because of its extreme retentive nature for nonpolar compounds. C18 is generally regarded as having the broadest spectrum of retention among bonded silica sorbents, since it retains most organic analytes from aqueous matrices. 

Bond Elut PSA is an alkylated amine sorbent that contains two different amino functionalities, one secondary and one primary. This gives a slightly higher pKa and ionic capacity compared to Bond Elut NH2. PSA has a significantly higher carbon load than most amino functional sorbents and thus is a better choice for polar compounds, which retain too strongly on Bond Elut NH2.

“QuEChERS” (Quick, Easy, Cheap, Effective, Rugged, and Safe) - Supel™ QuEPSA/C18 Tube, pack of 100, suitable for 2007.01 per AOACDispersive SPE (dSPE), often referred to as the "QuEChERS" method, is an emerging sample prep technique that is becoming increasingly popular in the area of multi-residue pesticide analysis in food and agricultural products. In dSPE, food/agricultural samples are first extracted with aqueous miscibl…

Ostro™ 96-well plate provides a novel solution for the cleanup of phospholipids in plasma and serum. Requiring minimal to no method development and using a simple protocol, this technology can be quickly implemented in order to optimize your laboratory's workflow. Removes significantly more phospholipids for cleaner extracts Improves reproducibility for more consistent, robust methods Increases throughput with easy-to-…

Waters offers PoraPak™ Rxn, a family of polymer-based chromatography products for superior cleanup of synthetic reactions. PoraPak Rxn products are available in two chemistries: PoraPak Rxn CX, a strong cation-exchange sorbent and PoraPak Rxn RP, a reversed-phase sorbent.PoraPak Rxn sorbents are based on copolymers that exhibit the following properties:Hard material that does not develop increasing back pressure with flowLitt…

EVOLUTE ABN is an advanced water-wettable polymer-based sorbent that extracts acidic, basic and neutral analytes from biological fluids and other aqueous matrices.

Advanced Polymeric SPE for Acidic Analytes

Complete Validation for PFAS Analysis in Compliance with ISO 2167

Clean, activated, and ready-for-use, 30 mesh copper granules remove unwanted elemental sulfur from pesticide and PCB extracts. Granules are much easier to use than copper powder or TBA and eliminate the need for toxic mercury.

Select pH Buffer Pouches - UCT has developed a line of premeasured “ready-to-use” phosphate and acetate buffer pouches. These pouches contain the correct quantity of reagent to quickly and accurately prepare buffers at the correct pH and concentration to simplify solid-phase extraction methods.

These sorbents are composed of a silica backbone bonded with hydrocarbon chains. They are used to extract compounds, which exhibit non-polar or neutral characteristics, from complex matrices. The C18 phase is the most popular phase.  UCT offers a range of hydrocarbon chain lengths from C2 to C30. In addition, we offer isobutyl, tertbutyl, phenyl, and cyclohexyl bonded phases.

Compounds are retained on hydrophilic sorbents through polar interactions including hydrogen bonding, pi-pi or dipole-dipole interaction.  Compounds typically extracted on a hydrophilic column include analytes which have polar groups, including amines, hydroxyls and carbonyls. Elution is performed by strong polar solvents. For these types of extractions UCT offers various types of base silica, Florisil®, Alumina's, cyanopropy…

This sorbent is composed of a silica backbone bonded with a carbon chain terminated by a negatively or positively charged functional group. Ion exchange interactions occur between a sorbent that carries a charge and a compound of opposite charge. This electrostatic interaction is reversible by neutralizing the sorbent and /or analyte. Ion exchange bonds can also be disrupted by introduction of a “counter ion” to compete with…

CLEAN SCREEN FASt THC is the newest sorbent in our FASt product lineup. It employs a process that uses positive pressure and a solid phase sorbent bed built with small pore frits to quickly and efficiently prepare urine samples for LC/MS analysis. This method eliminates timely centrifugation, reduces matrix suppression effects, and removes particulates greater than ~1μm. Samples can be diluted at a ratio as low as 1:1, which i…

The CLEAN SCREEN® THC column is copolymerized on a rigid, purified silica gel support. The two functional groups include a reverse phase, and an ion exchanger, primary amine. This column is commonly used for analyzing THC and its metabolites. It has dual functionality for acids and hydrophobic compounds.

Clean Screen® GHB is a patented mixed-mode column designed for the filtration extraction of ethylene glycol, butan diol, gamma hydroxy butyrate and butyrolactone.
