Da Sai Lu Special Chiral Chromatography ColumnThere are six types of compounds that are suitable for use on polysaccharide derivative chiral columns and difficult to separate. Specific types include: solvent resistant crown ether chiral chromatography columnCROWNPAK® CR-I(+)/CR-I(-), coated crown ether chiral chromatography columnCROWNPAK® CR(+)/CR(-)Ion exchange chiral chromatography columnCHIRALPAK® QD-AX/QN-AXBipolar ion exchange chiral chromatography columnCHIRALPAK ® ZWIX(+)/ZWIX(-), ligand exchange chiral chromatography columnCHIRALPAK® MA(+)/WHPolymethacrylate chiral chromatography columnCHIRALPAK® OP(+)/OT(+).
The chiral recognition mechanism of crown ether chiral columns: Under acidic conditions, the sample protonates into ammonium ions (- NH3+), forming reversible complexes with crown ethers, which can be used to separate amino acids and compounds with primary amine groups on the chiral center.
The ion exchange chiral column is a weak anion exchange HPLC chromatographic column with chiral selectivity, which is very suitable for separating acidic chiral compounds. It has significant chiral separation ability for chiral compounds containing carboxyl, phosphate, hypophosphite or sulfonic acid groups, and can also separate weakly acidic compounds such as phenols (coumarins).
The zwitterionic ion exchange chiral column can be used as a zwitterionic chiral stationary phase for separating free amino acids, and has significant stereoselectivity for zwitterionic chiral compounds, especially non derived amino acids and peptides.
