The predecessors to the immobilised columns, traditional CHIRALPAK® and CHIRALCEL® DAICEL coated polysaccharide Chiral Stationary Phases are made with a spherical high quality silica support onto which the polymeric chiral selector (amylose or cellulose derivatives) is physically coated. Due to the coated nature of these chiral supports, solvents should be carefully selected.
CHIRALPAK® AY-H, AZ-H & CHIRALCEL® OZ-H HPLC & SFC columns are phases that have been produced for several years by DAICEL. As the selectors are significantly different from existing DAICEL phases they allow new separations to be developed. These phases are now available as packed HPLC and SFC analytical and semi preparative columns. They are effective in developing new compound specific separations. They are an excellent complement in terms of recognition behaviour to the primary screen systems/sets of CHIRALPAK® IA, IB & IC or the alternative CHIRALPAK® AD, AS & CHIRALCEL® OD, OJ.
These columns are coated onto the silica support and hence can only be used with mobile phases of alkane/alcohol, acetonitrile/alcohol or mixed alcohol systems.
- New recognition profiles that allow new separations
- Complementary to existing DAICEL screening methodologies
- Excellent columns efficiency
- Easy use of the column
