The Clean Screen® FASt column is a novel approach to improved sample preparation for LC/MS analysis. The column employs a one step process to prepare urine samples for analysis of multiple drugs and metabolites. By quickly and efficiently reducing the amount of unwanted matrix and particulates in the final sample, the analysis can proceed with less chance of matrix suppression and LC column clogging.

Styre Screen® Extraction Columns contain an ultra clean, highly cross-linked styrene and divinylbenzene copolymer. The Styre Screen particles have an average particle size of 30 microns and a very high analyte capacity making them ideal for standard solid phase extraction applications. The increased analyte capacity means that less sorbent bed mass is needed which results in faster flow rates and less solvent use. Higher th…

Endcapped C18 - Enviro Clean SPE Cartridges Enviro-Clean® cartridges are designed for use by analysts that demand a clean, dependable and rugged product for low level environmental analyses. Our EC SPE Cartridges run the gambit of our sorbents for every configuration you require. C18, Octadecyl Hydrophobic, 1000 mg/6 mL. Part # EEC181M6

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…

The same clean polypropylene tubes we use in our own column assemblies are available as an empty tube. Available in 1mL through 150mL tube sizes. The flange on the lip means the columns are suitable for use with UCT's positive pressure manifold as well as with vacuum manifold systems.

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.

Clean Screen® ETG is a proprietary carbon blend column designed for the extraction of ethyl-glucuronide from urine.  Extracts are suitable for either GC/MS or LC/MS analysis.

CLEAN SCREEN FASt EtG is the newest sorbent in our FASt product lineup. Similar to the other products in the FASt line, 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 filtration device helps to combat the significant ion suppression EtG/EtS urine analysis typically suffers from using a standa…

Enviro-Clean 500mg/6mL cartridge HLDVB w/Polyethylene frits. UCT's new polymeric highly cross-linked DVB bead. It is used with EPA Methods  528, 529, 537, 553, 8141B and 8330.

Kit geared towards EPA Method 8270-Extraction of Acids, Neutrals, and Bases in 500 mL Water. Kit includes: 30 x 8270 Extraction Cartridges; 30 x Carbon Extraction Cartridges; 30 x Cartridge Adaptors; 12 x Large Volume Transfer Tubes.

UCT is excited to introduce our small and large push-thru glyphosate purification cartridges. Simply pass your aqueous extracts through either the small or large filter cartridge format to effectively remove all organic material and surfactants that hinder the chromatographic analysis of both glyphosate and glufosinate.

UCT's Enviro-Clean® Polymeric WAX Cartridges w/Polyethylene frits have been successfully utilized for the extraction of 26 diverse per- and polyfluoroalkyl substances (PFASs) in drinking water in addition to the 14 covered in the US EPA Method 537.
