Our Clean Screen® columns, the most recognizable UCT product line, is the industry standard for mixed-mode solid phase extraction for drugs of abuse and clinical drugs.
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
copolymeric 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 acids, neutrals and bases. This selectivity
makes Clean Screen ideal for both screening and confirmation analysis for virtually all drug categories.
Clean Screen DAU and THC columns are used extensively by forensic and clinical chemists including:
- Post Mortem Investigations
- Criminal Investigations
- Urine Drug Testing
- Athletic Drug Testing
- Racing Laboratories
- Therapeutic Drug Monitoring
- Medical Drug Screening
