Phases | Inertsil Diol

Key Benefits and Features of Inertsil Diol - Part of the Advanced Inertsil 3-Series of Phases    Unique selectivity in both reverse and normal phase modes    Analyze amino acids and water soluble vitamins without ion pair eluent modifiers    Analyze sugars with exceptional column lifetime    Longer retention than silica in normal phase mode    Exhibits normal phase characteristics with water / acetonitrile eluents Inertsil Diol (dihydroxypropyl bonded phase) takes advantage of the dihydroxypropyl bonded phase's unique characteristics in both normal and reverse phases. In normal phase mode, the diol phase provides an alternative selectivity to silica, often with increased retentivity which helps improve separating power. In reverse phase mode, compounds such as amino acids and water-soluble vitamins are nicely separated with unique selectivity with simple eluents.  Sugars are also well separated and this diol phase shows long column life analyzing sugars - unlike many other phases used for sugar analysis. Inertsil Diol is available in 5 micron particle size in column configurations ranging from capillary to 50mm ID preparative sizes. The Inertsil 3-series represents a major advance in performance over the original Inertsil 2-Series. Inertsil 3-Series phases, including ODS-3, ODS-3V, ODS-P, ODS-EP, C8-3, Ph-3, CN-3, NH2, SIL-100Å, are based on a purer, higher surface area silica which is specially manufactured to provide maximum bonded phase coverage.  The result is a series of columns which provide excellent peak shapes using simple eluents while operating at low pressure.          Particle Size Particle Shape Surface Area Pore Size Pore Volume Silica Purity Bonded Phase End- Capping Carbon Load pH Range USP Code 3, 5 µm Spherical 450 m2/g 100Å 1.05 mL/g 99.999% Dihydroxy- propyl   20% 2 - 7.5 L20
