SUMICHIRAL OA-2000 series

Features

  • Mainly used for normal phase systems
  • Only OA-2500 is mainly used for reversed-phase systems. However, applicable for LC-MS when ammonium acetate/methanol solution is used (water is not usable as the mobile phase)
  • Ion bonding type columns are also available
    Normal phase systems only (acid or base cannot be added)
  • Possible to reverse the elution order

Supports SFC (supercritical fluid chromatography)
