Merck, 14023AST, Astec® CHIROBIOTIC® TAG Chiral HPLC Column

The removal of three carbohydrate moieties gives CHIROBIOTIC® TAG complementary selectivity to CHIROBIOTIC® T. Resolution is enhanced toward many of the amino acids, α, β, γ and cyclic, and especially sulfur-containing methionine, histidine and cysteine. A number of neutral molecules like the oxazolidinones, hydantoins and diazepines have shown enhanced resolution and, more remarkably, in the single solvents like methanol, ethanol and acetonitrile. Some acidic molecules have also shown increased selectivity. •Bonded phase: Teicoplanin aglycone •Operating pH range: 3.0 - 6.8 •Particle diameter: 5, 10 or 16 μm •Pore size: 100 Å
