Daicel 13022 CHIRALCEL OC Coated Polysaccharide Derivative Guard HPLC Chiral Column, 4.6mm, 50mm, 10µm
The surface of the silica gel is coated with cellulose-tris(phenylcarbamate)
USPL70 specified packing, oxaliplatin special column (CHIRALCEL® OC-H)
OC is a polysaccharide derivative normal phase coated chiral column, and the surface of the silica gel is coated with cellulose-tris(phenylcarbamate).
OC is currently the most widely used chiral filler in the world. The excellent separation ability and tolerance of OC column have been reported in various literatures.
CHIRALCEL ® OC-H / CHIRALCEL ® OC is used in the normal phase mobile phase
Filler particle size | CHIRALCEL ® OC-H: 5μm CHIRALCEL ® OC: 10μm |
---|---|
pressure | In order to extend the service life of the chiral column, it is recommended to keep the pressure below 30MPa. (For CHIRALCEL ® OC columns, please keep the pressure below 10MPa) |
temperature | 0~40°C |
Storage solvent | CHIRALCEL ® OC-H: Ethanol/Methanol = 30/70 (v/v) CHIRALCEL ® OC: 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.
- 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 pure Ethanol 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.
