Daicel 19525 CHIRALPAK AD-3 Coated Polysaccharide Derivative Analytical HPLC Chiral Column, 4.6mm, 250mm, 3µm
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) |
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. 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
