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

USP L51 specified packing

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

AD is currently the most widely used chiral filler in the world. The excellent separation ability and tolerance of the AD column have been reported in various literatures.

CHIRALPAK ® AD-3 / CHIRALPAK ® AD-H / CHIRALPAK ® AD 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.

pressure

In order to extend the service life of the chiral column, it is recommended to keep the pressure below 30MPa.

(For CHIRALPAK ® AD columns, please keep the pressure below 10MPa)

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
