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.

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)

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.
