Daicel 20256 CHIRALPAK® AS-V Amylose Tris Coated Semi-Preparative HPLC Chiral Column, 50mm, 500mm, 20µm
CHIRALPAK® AS-V bulk stationary phase consists of a 20 µm silica support onto which the polymeric chiral selector : amylose tris ((S)-a-methylbenzylcarbamate) has been physically coated. Due to the coated nature of these chiral supports, solvents should be carefully selected
Amylose tris [(S)-methylbenzylcarbamate] coated on a 20µm silica support
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.
- The mobile phase should be displaced with Storage Solvent (Hexane / 2-propanol 9:1) when stored for more than one week.
- When washing is required, use Hexane / Ethanol 80:20 (v/v) at an appropriate flow rate for 3 hours
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.
