WebCHIRALDEX 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 d f 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. WebHere we describe the separation of the enantiomers of ephedrine, pseudoephedrine, chlorinated intermediates and methylamphetamine using fluorinated acid anhydrides as chemical derivatization reagents prior to gas chromatographic analysis on a 2,3-di-O-methyl-6-t-butyl silyl-β-cyclodextrin stationary phase (CHIRALDEX™ B-DM).
Astec Chiraldex® GC Capillary Columns - Analytical Columns
WebThrough special derivatization techniques, the concentration of the cyclodextrin in the CHIRALDEX™ B-DM has been substantially increased in the polysiloxane carrier. This phase is very useful for a number of free acids and bases. The B-DM is able to perform most of the separations done on a beta-permethylated phase, but with higher resolution. WebJan 1, 2013 · The Chiraldex B-DM column separated 11 analytes with baseline resolution. Compounds 10 and 15 – 17 were partially separated on this column under the same conditions used with other columns. All these four CD-CSPs show excellent chiral separation abilities, and examples of the best and worst separation results obtained are … sudia to pakistan driceat flight
