Daicel Chiral Ligand Exchange Columns

Daicel chiral ligand exchange columns CHIRALPAK WH and CHIRALPAK MA(+) are designed for separation of alpha amino acids and other acidic chiral molecules. They are compatible with reversed phase HPLC and can be used with aqueous solutions of copper sulfate.

CHIRALPAK WH – proline chiral selector
CHIRALPAK MA(+) - N,N-dioctyl-L-alanine chiral selector

  • Ligand exchange type columns
  • Suitable for free amino acid, amino acid derivatives, and carboxylic acids
  • CHIRALPAK WH is designated USP L32
  • Use with aqueous copper sulfate mobile phase
  • Strongly basic solvent modifiers or sample solutions must be avoided as they are likely to damage the silica used in the column
