Daicel 19744 CHIRALPAK AD-RH Coated Polysaccharide Derivative Semi-Preparative HPLC Chiral Column, 20mm, 150mm, 5µm
The surface of the silica gel is coated with amylose-tris(3,5-dimethylphenylcarbamate)
USP L51 specified packing
CHIRALPAK ® AD-3R / CHIRALPAK ® AD-RH is a reverse-phase coated chiral column for polysaccharide derivatives. The surface of the silica gel is coated with amylose-tris(3,5-dimethylphenylcarbamate). Suitable for use in reverse phase mobile phases.
Inverted series chiral column for CHIRALPAK ® AD-3 / CHIRALPAK ® AD-H.
Suitable for the analysis of water-soluble samples, or samples with specific requirements for pH.
Suitable for LC/MS.
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. |
pH value | pH 2.0~9.0 (to avoid using extreme pH values to prevent damage to the stationary phase of the silica matrix) |
temperature | 5~40°C, |
Storage solvent | H 2 O/Acetonitrile = 60/40 (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
