Xtrackt Hydrophobic + Aminoethyl H/F 500mg/3mL, 50 pkg

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.

PSA is an alkylated amine sorbent that contains two different amino functionalities – one secondary and one primary. This gives a slightly higher pKa and ionic capacity compared to NH2. PSA has a significantly higher carbon load than most amino functional sorbents, thus is a better choice for polar compounds, which retain too strongly on typical NH2 matrices.
