• Hydrophilic polymer---No column conditioning required, eliminates column drying problem
  
  
• 25 micron particle size--- Provides selective and efficient recoveries of drugs of abuse.
  
  
• High cross linking----Provides a rigid polymer that is stable from pH 1 to 14 and eliminates troublesome ph adjustment steps in extraction process
  
  
• Polymer based chemistry--- Excellent lot-to-lot reproducibility. Single source manufacturing
  
  
• Convenient bulk packaging—Provides all the benefits of polymer chemistry at prices
  comparable to silica columns.

Trace-B, Hydrophilic polymer/ Strong Cation Exchanger, 25 micron, 300A. This material exhibits excellent selectivity for extracting basic drugs from biological fluids. Dual mode mechanism of extraction used to achieve ultra high purity extracts. This material is widely applicable for many drugs of abuse including opiates, amphetamines and cocaine.


Trace-N, Hydrophobic polymer/ Weak Anion Exchanger , 10 micron, 300A. This material exhibits excellent selectivity for extracting neutral drugs from biological fluids. Dual mode mechanism of extraction used to achieve ultra high purity extracts. This material is excellent for the extraction of THC and its metabolite from urine.
