Daicel 85345 CHIRALPAK ® IE Semi Preparative HPLC Chiral Column, Polysaccharide Derivatives Solvent-based Chiral Columns 20mm, 250mm, 5µm
The surface of the silica was covalently bound with amylose - tris (3,5-dichlorophenylcarbamate)
IE solvent-resistant chiral column, the amylose-tris (3,5-dichlorophenylcarbamate) covalently bonded to the surface of the silica gel.
Unrestricted use of solvents, a wide range of dissolution conditions, the use of any miscible solvent as a mobile phase, dissolved samples, chiral column regeneration.
Examples of solvents that can be used:
Normal phase: n-Hexane, IPA, EtOH
Special mobile phase: Ethyl acetate, CH 3 Cl, THF, MTBE
Inverted: H 2 O, of IPA, MeOH
Parameters
Filler particle size | CHIRALPAK ® IE-3: 3μm CHIRALPAK ® IE: 5μm |
---|---|
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 |
temperature | 0 ~ 40 ℃ |
Save the solvent | CHIRALPAK ® IE-3: n-Hexane / 2-Propanol = 90/10 (v / v) CHIRALPAK ® IE: n-Hexane / Ethanol = 90/10 (v / v) |
Column Storage
For column storage, remove the acidic or basic additives by flushing the column with the same mobile phase without the additive. Columns can be stored with the additive-free mobile phases.
Operating these columns in accordance with the guidelines outlined here will result in a long column life.
Mobile phase
i CHIRAL serise series can use various types of solvents as the mobile phase or dissolve the sample solvent (note the mutual solubility between solvents), for example as follows:
N-Hexane | Dimethylsulfoxide (DMSO) |
Isopropanol (IPA) | ● Chloroform (Trichloromethane) |
● Methyl tert-butyl ether (MTBE) | ● Methyl cyanide |
● Dichloromethane | ● Methylbenzene |
Tetrahydrofuran (THF) | 1,4-Dioxane |
● Acetic ether | Water (H 2 O) |
