General description
CHIRALDEX column kit contains three GC CSPs that cover the widest possible range of enantioselectivity: G-TA, B-DM and B-DA, in the popular 30 m x 0.25 mm, 0.12 μm df dimensions. The G-TA separates the greatest number of enantiomers, often with high enantioselectivity. The B-DM separates the widest variety of different structural types. The B-DA is best suited for larger multi-ring structures. Eighty-five percent of analytes which exhibit enantioselectivity on cyclodextrin based chiral stationary phases will give enantioselectivity on one of these phases. Realize considerable savings over the columns purchased separately.
Kit contents: One 30 m × 0.25 mm I.D., 0.12 μm column of each type: CHIRALDEX G-TA, B-DM and B-DA
Kit contents: One 30 m × 0.25 mm I.D., 0.12 μm column of each type: CHIRALDEX G-TA, B-DM and B-DA

The enantiomers of dialkyl 2,3-pentadienedioate undergo interconversion during gas chromatographic separation on chiral stationary phases. In this paper the on-column apparent interconversion kinetic and thermodynamic activation data were determined for dimethyl, diethyl, propylbutyl and dibutyl 2,3-pentadienedioate enantiomers by gas chromatographic

A new gas chromatography (GC) method is presented for analysing both the conversion and the enantiomeric excess (e.e.) of samples from alcohol dehydrogenase reactions. The chiral compounds studied were a series of saturated, straight chain alcohols, ranging from 2-butanol to

The separation of 17 chiral sulfoxides and eight chiral sulfinate esters by gas chromatography (GC) on four derivatized cyclodextrin chiral stationary phases (CSPs) (Chiraldex G-TA, G-BP, G-PN, B-DM) is presented. Many of these compounds are structural isomers or part of
