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

Filler particle size

CHIRALCEL ® OA: 10μm

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.
