CHROMTECH columns
Chiral HPLC columns
These protein-based columns are suitable for several types of compounds; basic compounds can be separated on both CHIRALPAK® AGP and CHIRALPAK® CBH, acidic and neutral compounds can be separated on both CHIRALPAK® AGP and CHIRALPAK® HSA. However, as CHIRALPAK® AGP is a column with an extremely broad applicability, this column should be chosen first, if the analyte has not been separated on any of the columns. There are, however, some types of compounds where one of the other columns may be the first choice :
Extremely broad applicability. We believe that this chiral phase as one of the broadest analytical selectivities of any chiral phase. Separates all kinds of compounds :
- amines (primary, secondary, tertiary and quartenary)
- acids (strong and weak)
- nonprotolytes (amides, esters, alcohols)
- CHIRALPAK® CBH
Narrower applicability than CHIRALPAK® AGP. Separates compounds containing one or more basic nitrogens together with one or more basic nitrogens together with one or more hydrogen accepting or hydrogen donating groups (alcohol, phenol, carbonyl, amide, ether, sulphoxide, ester, etc.).
Narrower applicability than CHIRALPAK® AGP. Separates preferentially weak and strong acids and non-protolytic compounds.
