Silicycle SiliaPrepX WAX SPE is a polystyrene-divinylbenzene copolymer functionalized by a weak anion exchanger used to catch and release strong acidic compounds (pKa <2). It is highly stable in organic solvents.
Typical applications include strong acidic compounds and metabolites from biological fluids and tissues, and sulfonates and perfluorinated surfactants.
Features
- SiliaPrepX WAX is a polymeric weak anion exchanger sorbent
- Suitable for extracting stongly acidic compounds from a wide range of matrices
- Exceptional lot-to-lot reproducibility
- High recovery and yield
- Very good separation and flow characteristics
- No contamination from the matrix
- pH Stability from 0 to 14
- Standard SiliaPrepX cartridges are made with flanged polypropylene (PP) tubes and 20 μm polyethylene (PE) frits
- Larger sizes are also available under SiliaSep OT branding
