Daicel 14094 CHIRALCEL OD Coated Polysaccharide Derivative Analytical HPLC Chiral Column, 2.1mm, 150mm, 10µm
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.

---|---|
pressure | We recommend you to use it within the range not exceeding 30 MPa in order to use the column for a long time. (However, for CHIRALCEL OD, we recommend that you use it within the range not exceeding 10 MPa.) |
temperature | 0 to 40 ° C |
Sealing solvent | n - Hex./IPA=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
