UCT Clean Screen - Analytical demand for more efficient, robust and clean extraction of drugs from biological matrices led to the development of Clean Screen sorbents. Since 1986, Clean Screen has led the industry with dependable and reproducible Solid Phase Extraction products and applications. Clean Screen phases are true co-polymeric sorbents that contain hydrophobic and ion exchange functional groups uniquely polymerized to a silica substrate. The design and quality of Clean Screen provides superior sample clean up, recovery and reproducibility. Mixed-mode separations allow maximum selectivity for extraction of acidic, neutral and basic compounds. This selectivity makes Clean Screen ideal for both screening and confirmation analysis for virtually all drug categories.are available with many sorbents in any configuration you require.

Enviro-Clean solid-phase extraction (SPE) cartridges are designed specifically for the isolation and purification of environmental analytes such as pesticides, herbicides, polyaromatic hydrocarbons, polychlorinated biphenyls and other environmentally related compounds. By utilizing ultra-clean extraction sorbents along with chemically resistant PTFE frits, an end-user not only has the ability to purify complex matrices, but also reduce ion suppression or enhancement, and most importantly enrich compunds resent at trace concentration levels.

Styre Screen extraction sorbents are formulated with an ultra clean, highly cross-linked styrene and divinylbenzene copolymer sorbent. The sorbent can be functionalized with any of the same phases as our silica based sorbents. Possibilities include standard hydrophilic, hydrophobic, or ion exchange functionalities as well as copolymeric phases such as the DBX phase. Styre Screen particles have an average particle size of 30 microns. This polymeric sorbent has a very high analyte capacity, ideal for standard solid phase extraction applications. This higher capacity translates into a lower bed mass requirement in order to retain the same analyte quantity as a traditional silica particle. Lower bed mass also means extractions can be run at faster flow rates and with less solvent usage. The Styre Screen sorbent also eliminates the need for an initial column conditioning step. All these attributes ultimately result in excellent cost benefit
