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.
