The surface of the silica gel is coated with cellulose-tris(3,5-dimethylphenylcarbamate)

USP L40 specified packing

OD is a polysaccharide derivative normal phase coated chiral column, and the surface of the silica gel is coated with cellulose-tris(3,5-dimethylphenylcarbamate).

OD is one of the most widely used chiral fillers in the world. The excellent separation ability and tolerance of OD columns have been reported in various literatures.

CHIRALCEL ® OD-3 / CHIRALCEL ® OD-H / CHIRALCEL ® OD are suitable for use in normal phase mobile phases.

Provide regular analytical columns of different specifications, micro-diameter columns with an inner diameter of 2.1mm, and semi-preparative columns and preparation columns with different inner diameters. You can select the appropriate specifications according to the experimental needs.

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.  For alkane containing mobile phases, flush the column with Storage Solvent (Hexane / 2-propanol 9:1) when stored for more than one week. 
  • For columns dedicated to polar solvents, flush the column with the regular mobile phase without the additive. 
  • When washing is required, flush pure Ethanol for 3 hours. (Columns used with alkane/alcohol mobile phase only). 
  • Before flushing with 100% Ethanol use 100% 2-propanol as a transition mobile phase. 


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. 
  • Operating this column in accordance with the guidelines outlined here will result in a long column life
