This document is a user manual for the chiral column CHIRALCEL® OJ-H, which describes the filler structure, factory storage solvent, operating limitations, flow direction, column pressure range, and chromatographic conditions.
The CHIRALCEL OJ-H is a cellulose‑derived chiral column designed for analytical and semi‑preparative separations. It features a 5 µm silica‑based packing and is supplied with a storage solvent of n‑hexane/isopropanol (90:10 v/v).
The manual outlines operating limits such as temperature (0 to 40 °C), pressure (< 50 Bar ideal, up to 100 Bar safe), and flow rates for different column dimensions. It also gives detailed recommendations for mobile phase composition, solvent compatibility, and cleaning procedures to ensure optimal column performance and longevity. This manual is written in Chinese.
| Particle size | 5 µm |
|---|---|
| Analysis column dimensions | 150 × 4.6 mm |
| Semi‑preparative column dimensions (10 mm ID) | 250 × 10 mm |
| Semi‑preparative column dimensions (20 mm ID) | 250 × 20 mm |
| Maximum pressure | 100 Bar |
| Temperature range | 0 to 40 °C |
| Typical flow rate (analysis column) | 1.0 ml/min (max 1.5 ml/min) |
| Recommended storage solvent | n‑hexane / isopropanol (90:10 v/v) |
Store the column in a mixture of n‑hexane and isopropanol at a 90:10 volume ratio.
Ideal pressure is below 50 Bar, but the column can safely operate up to 100 Bar.
Acetone, chloroform, DMF, DMSO, ethyl acetate, dichloromethane, and THF should not be used.
