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 polymerised 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.
CLEAN SCREEN® DAU
This column is co-polymerised on a rigid, purified silica gel. The two functional groups include a reverse phase and an ion exchanger (Benzenesulfonic acid). This column is commonly used for analysing a wide range of drugs of abuse, including acidic, basic and neutral drugs.
CLEAN SCREEN® GHB
This column is co-polymerised on a rigid, purified silica gel. Most analytical methods are based upon interconversion to lactone and chemical derivatization to form the TMS derivative. This column is for the extraction of FREE GHB.
CLEAN SCREEN® BNZ
This column is co-polymerised on a rigid, purified silica gel. The phase is polar organic phase. This column is commonly used for analysing a wide range of benzodiazepines with exceptional recovery of 7-amino metabolites.
CLEAN SCREEN® THC
This column is co-polymerised on a rigid, purified silica gel. The two functional groups include a reverse phase and an ion exchanger (primary amine). This column is commonly used for analysing THC and its metabolites.
CLEAN SCREEN® ETG
This column is a specialised activated carbon column. It is used specifically for analysing ethyl glucuronide in urine by both LC/MS and GC/MS.
CLEAN SCREEN® RSV
Reduced Solvent Volume is a small particle, small bed SPE column designed for reduced solvent usage and more economical extractions. Reverse phase and ion exchange co-polymeric bonded phase for therapeutic drugs and drugs of abuse testing
