Descripción general

CHIROBIOTIC® R, based on the ristocetin A glycopeptide covalently bonded to high purity silica particles, has shown particular applicability to enantiomers of anionic compounds. Selectivity on CHIROBIOTIC® R strongly correlates to the organic modifier, favoring the alcohol-type mobile phases by a large margin.

  • Bonded phase: Ristocetin A
  • Operating pH range: 3.5 - 6.8
  • Particle diameter: 5, 10 or 16 μm
  • Pore size: 100 Å
