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

QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) is a sample extraction and clean-up technique used for the analysis of multiple pesticide residues in agricultural products. UCT manufactures a wide variety of pre-filled tubes and reagent pouches for all QuEChERS method variations including PSA, C18, buffers, anh. MgSO4, NaCl, ChloroFiltr, and carbon.

The FASt Well Plate is a novel approach to improved sample preparation for LC/MS analysis. The well plate 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.

High purity, Type B, spherical silica support. 100A pore size. 1.8um, 3um, & 5um partical sizes. Variety of stationary phases.

The QuEChERS Clean-up step is rapidly completed using the QuICK QuEChERS cartridge. This self-contained cartridge contains 110 mg of anhydrous MgSO4 and 180 mg of PSA. Placed on the end of a disposable syringe, the QuEChERS extract is pushed through directly into a sample vial for analysis. Clean-up is equivalent to dSPE clean-up, but faster and easier, eliminating the need for centrifugation.

Activated carbon cartridge product EU52112M6 with 2 grams carbon/6 mL cartridge has proven to be effective for the extraction of nitrosamines in drinking water Method 521.  EPA Method 522 for 1, 4 dioxane is extracted using one of two options.  EU52112M6 is suitable for Option 1 which uses this product with 2 grams carbon in a 6 mL cartridge.

Pre-packed 6 ml anion exchange SPE cartridges are made to the exact specification of EPA Method 548 to assure high capture efficiency and consistent results for excellent analytical reproducibility.

Airborne laboratory contamination may interfere with solid-phase extraction results. This problem is easily prevented by using the Zero-Blank filter. Using an adaptor (included), this cartridge is fitted on top of the SPE cartridge during the drying step and captures potential contamination making results more accurate.

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.

Chlorophyll in QuEChERS extracts must be removed to reduce potential instrument downtime. This is removed from extracts using graphitized carbon black (GCB) Unfortunately, GCB also removes planar analytes reducing analytical accuracy. ChloroFiltr®, used in place of GCB in dSPE tubes, removes unwanted chlorophyll without removing pesticides or environmental analytes. No change in procedure are required.

When clean plastic cartridges are not clean enough. 6 mL glass SPE cartridges can be packed with your choice of UCT sorbent using PTFE frits and individually sealed in certified Mylar for purity.

Enviro-Clean 500mg/6mL cartridge PSDVB w/Polyethylene frits. It is used with EPA Methods 526, 527, 528, 529 and 8330.

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.

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…

XtrackT® columns are gravity-flow SPE columns that allow for extraction of acids, neutrals, bases in viscous samples such as equine urine, post-mortem blood and tissues, amniotic fluid, and meconium.

The Universal Vacuum Manifold system accommodates 24, 48 and 96 well plate configurations. This system includes a collection plate, extraction plate, manifold and vacuum gauge waste base for all wellplates.

Universal C18 - Enviro-Clean SPE Cartirdges Enviro-Clean® cartridges are designed for use by analysts that demand a clean, dependable and rugged product for low level environmental analyses. Universal C18 is used for the extraction of pesticides, herbicides and PCBs, etc.Part # ECUNIC18

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.
