Phase Description Application
Pharmaceutical
HybridSPE-PPT Phospholipid removal from plasma and serum samples to reduce ion suppression in LC-MS
Supel-Select HLB SPE Hydrophilic modified styrene polymer ideal for extracting a very broad range of compounds from aqueous samples… at a price you desire!
Discovery DSC-MCAX Mixed-mode cation exchange for superior selectivity/sample cleanup when extracting basic compounds (most pharmaceuticals) from biological fluids (e.g., plasma, urine, etc.)
Polymer SAX Rezorian™ Cartridge Strong cation and anion exchanger on a styrene base particle. Offers much higher ion-exchange capacity Polymer SCX Reversible Tube than silica based ion-exchangers
Supelclean LC-4 (wide pore) Used for desalting proteins/peptides and other macromolecules
SupelMIP™ SPE Tubes Molecular imprinted polymers for the highly selective extraction of trace analytes in difficult sample matrices
Food & Beverage
