CHIRALPAK® IA The first imobilised amylose column which expands the application coverage of this polysaccharide support and broadens the choice of mobile phases that may be used in chiral chromatography. The extended choice of solvents opens up new possibilities for unique selectivities in the separation of enantiomers, together with enhanced solubility of samples.

CHIRALPAK® AD The most versatile chiral column available. Use on compounds with aromatic, amide, carbamate, ester groups, alkyl amines, and compounds with multiple stereogenic sites.

CHIRALPAK® AS If no separation is observed on CHIRALPAK AD, this column should be tested second. Particularly appropriate for ß lactams, glycidol derivatives, epoxides, acids, natural products and heterocyclic compounds with a chiral centre on the ring.

CHIRALCEL® OD If CHIRALPAK AD shows some resolution, this column may provide improved separation. Particularly effective for beta blockers, compounds with similar functionality, steroids. Examples: alprenolol, atenolol, flavanone, metoprolol, oxprenolol, pindolol and propranolol.

CHIRALCEL® OJ If CHIRALPAK AS shows an indication of separation then this column should also be evaluated. Particularly appropriate for the following (and compounds with similar structures): ibuprofen, ketamine, methadone, nicotine, steroids, acebutolol, albuterol, chlophedianol, mianserin, and other compounds with a bulky substituent at the chiral centre.

CHIRALCEL® OA Speciality column, particularly if the chemical is a low molecular weight racemate.

CHIRALCEL® OB Test on compounds that show some indication of separation on CHIRALPAK ASA or CHIRALCEL OJ. Examples: benzoin, 1,3 diacetoxybutane 2-acetoxy-3-phenylpropane, a-phenylethanol, 2-phenylcyclohexanone.

CHIRALCEL® OC Speciality column to resolve compounds that show partial resolution on CHIRALPAK AD and/or CHIRALCEL OD.

CHIRALCEL® OF Speciality column to resolve compounds that are not separated on the more versatile "Gold Medal" columns. Especially suited for prostaglandins. Note that this is a very retentive column.

CHIRALCEL® OG Speciality column, especially suited for compounds with partial separation on CHIRALCEL OD and CHIRALCEL OC.

CHIRALCEL® OK Speciality column to resolve compounds that are not separated on the more versatile "Gold Medal" columns. Note that this is a very retentive column.

CHIRALCEL® CA-1 Suitable for compounds with aromatic and carbonyl groups.

CHIRALCEL® OB-H Use to resolve compounds that require higher number of plates than available with CHIRALCEL OB column.

CHIRALCEL® OD-H Use to resolve compounds that require higher number of plates than with CHIRALCEL OD column.

CHIRALCEL® OD-RH Reversed phase type of CHIRALCEL OD. Can be used with neutral, acidic and basic compounds, including verapamil, propranolol, pindolol, diphenylethylamine, and other compounds separated in normal phase on CHIRALCEL OD.

CHIRALCEL® OJ-RH Reversed phase type of CHIRALCEL OJ. Can be used with neutral, acidic and basic compounds, including ibuprofen, flurbiprofen, 1-(1 -naphthyl) ethanol, 1 -(1 -naphthyl) ethylamine, and most of the compounds separated in normal phase on CHIRALCEL OJ.

CROWNPAK® CR Amino acids and compounds with a primary amino group, near an asymmetric center, including dipeptides. The CROWNPAK CR (-) provides reverse order of elution relative to CROWNPAK CR (+).

CHIRALPAK® OP(+) Compounds possessing an aromatic group; Examples: Troger’s base, tocopherol acetate.

CHIRALPAK® OT(+) Compounds possessing an aromatic group; Examples: binaphthol, salithione.

CHIRALPAK® MA(+) a-hydroxy carboxylic acids, a-amino acids.
CHIRALPAK® WE Amino acid derivatives, including alanine, lysine.
CHIRALPAK® WH Amino acid derivatives, including histadine, valine, phenylalanine.
CHIRALPAK® WM Amino acid derivatives.
