Feature
Ligand Exchange Chiral Stationary Phases
CHIRALPAK® WH / CHIRALPAK® MA(+) columns
The chiral stationary phases in these columns are made of amino acids and its derivatives coated or bonded to silica supports ( with a particle size of 10μm for WH and 3μm for MA (+) ) . Since these columns are ligand-exchange type columns, the standard mobile phase to use is an aqueous solution of CuSO4 (0.1 to 2mM) . These columns can tolerate organic moditifiers such as Methanol and Acetonitrile according to the specifications in the instruction manual.
Polymethacrylate Chiral Stationary Phases
CHIRALPAK® OP(+) / CHIRALPAK® OT(+) columns
The chiral selector is a chiral synthetic methacrylate polymer coated onto a 10μm silica suppor t. The best chromatographic results are obtained using 100% Methanol as mobile phase. The polymer used for the CHIRALPAK OT (+) column is very delicate and is slowly degraded by alcohols. To avoid this phenomenon, we recommend to run the analyses at low temperatures ( 0~5 ).
