Daicel 20311 CHIRALPAK AS-H Coated Polysaccharide Derivative Guard Cartridges (Pack of 3), 4mm, 50mm, 5µm
The surface of the silica gel is coated with amylose-tris(S)
-α-methylphenylcarbamate)
AS is a polysaccharide derivative normal phase coated chiral column, and the surface of the silica gel is coated with amylose-tris(S)-α-methylphenylcarbamate.
AS is currently the most widely used chiral filler in the world. The excellent separation ability and tolerance of AS column have been reported in various literatures.
CHIRALPAK ® AS-3 / CHIRALPAK ® AS-H / CHIRALPAK ® AS are 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 | CHIRALPAK ® AS-3: 3μm CHIRALPAK ® AS-H: 5μm CHIRALPAK ® AS: 10μm |
---|---|
pressure | In order to extend the service life of the chiral column, it is recommended to keep the pressure below 30 MPa. (For CHIRALPAK ® AS columns, please keep the pressure below 10MPa) |
temperature | 0~40°C |
Storage solvent | n-Hexane/2-Propanol = 90/10 (v/v) |
If you wish to use this chiral column in a reversed phase mobile phase, please see CHIRALPAK ® AS-3R / CHIRALPAK ® AS-RH .
If a chiral compound with low solubility in an alkane/alcohol system is encountered, it is recommended to use a bonded chiral column (solvent-resistant chiral column) to try other mobile phase conditions.
