Daicel chiral anion exchange CHIRALPAK QN-AX and QD-AX columns are packed with weak anion-exchange chiral stationary phases based on complementary quinine (QN) and quinidine (QD) derivatives. They are designed for separation of chiral acids, such as N-derivitized amino acids and phenols. Due to their pseudo-enantiomeric character, they usually reveal reversed elution order for opposite enantiomers.
CHIRALPAK QN-AX - O-9-(tert-butylcarbamoyl) quinine chiral selector
CHIRALPAK QD-AX - O-9-(tert-butylcarbamoyl) quinidine chiral selector
Features
- Weak anion-exchange chiral stationary phases

- Suitable for HPLC (polar organic phase and hydro-organic phase) and SFC methods
- Compatible with all common HPLC solvents
- pH range is pH 2 to 8
