Product description

Product description

XtrackT® large particle bonded phases allow for uniform gravity flow for most blood and urine samples. A single column provides extraction for a broad spectrum of compounds with selective elution of acid, neutrals, steroids and bases. XtrackT® large particle (80–200 μm) silica gels are available with hydrophobic, hydrophilic, ion exchange or copolymeric phases, including DAU mixed mode. XtrackT® is recommended for viscous sample matrices or for gravity flow applications.

WCX is a mid-polarity sorbent and weak cation exchanger. It can be used with a wider range of counter-ions than lower pKa sorbents like SCX, and will demonstrate easier elution of quaternary amine functionalized analytes.
