The surface of the silica gel is coated with cellulose-triacetate
OA is a positive-phase coated chiral column of polysaccharide derivative, and the surface of the silica gel is coated with cellulose-triacetate.
CHIRALCEL ® OA is suitable for use in normal phase mobile phases.
Parameters

pressure |
In order to extend the service life of the chiral column, it is recommended to keep the pressure below 10 MPa. |
temperature | 0~40°C |
Storage solvent |
n-Hexane/2-Propanol = 90/10 (v/v) |
Column Care
- The use of a guard column is highly recommended for maximum column life.
- Samples should be dissolved in the mobile phase and should be filtered through a membrane filter of approximately 0.5µm porosity.
- The mobile phase should be displaced with Storage Solvent (Hexane / 2-propanol 9:1) when stored for more than one week.
- When washing is required, use pure Ethanol at an appropriate flow rate for 3 hours.
Important Notice
STRONGLY BASIC solvent modifiers or sample solutions MUST BE AVOIDED, because they are likely to damage the silica gel used in this column.
