Daicel 17395 CHIRALCEL OJ-H Coated Polysaccharide Derivative Analytical HPLC Column, 250mm, 2.1mm, 5µm
The surface of the silica gel is coated with cellulose-tris(4-methylbenzoate)
USP L80 specified packing
OJ is a polysaccharide derivative normal phase coated chiral column, and the surface of the silica gel is coated with cellulose-tris(4-methylbenzoate).
OJ is currently the most widely used chiral filler in the world. The excellent separation ability and tolerance of OJ column have been reported in various literatures.
CHIRALCEL ® OJ-3 / CHIRALCEL® OJ-H / CHIRALCEL ® OJ is 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.
| Filler particle size | CHIRALCEL® OJ-3: 3μm CHIRALCEL® OJ-H: 5μm CHIRALCEL® OJ: 10μm |
|---|---|
| pressure | In order to extend the service life of the chiral column, it is recommended to keep the pressure below 30MPa. (For CHIRALCEL ® OJ 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
