XtrackT PCH - Propylsulfonic Acid 

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 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.
