Ultrasep ES DIISO is a silica-based HPLC column with a diisopropyl bonded phase, designed to provide unique hydrophobic and steric selectivity. The branched isopropyl groups create a distinctive surface environment that improves separation of structurally related compounds and moderately hydrophobic analytes, offering an alternative selectivity to conventional straight-chain alkyl phases.
With its tailored bonding chemistry, Ultrasep ES DIISO delivers reproducible results, sharp peak shapes, and robust stability under routine analytical conditions. This makes it an excellent choice for laboratories requiring orthogonal selectivity in pharmaceutical, biochemical, and chemical separations.
Ultrasep ES DIISO combines branched hydrophobic selectivity with robustness and reproducibility – the reliable choice for laboratories seeking alternative separation mechanisms in HPLC.
