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)
