一般說明
CHIRALDEX 色谱柱套件包括三种气相色谱手性固定相 (CSP),其涵盖了尽可能宽的对映立体选择性范围:G-TA、B-DM 和 B-DA,并且采用通用的 30m×0.25mm,0.12μm df 尺寸。G-TA 能够分离最大数量的对映异构体,通常具有高对映立体选择性。B-DM 能够分离各式各样的不同结构类型。B-DA 最适合分离较大的多环结构。在环糊精手性固定相上具有对映立体选择性的分析物中百分八十五能够在这三种相的其中一种上具有对映立体选择性。与单独购买色谱柱相比,这可节省大量开支。
套件包括:CHIRALDEX G-TA、B-DM 和 B-DA 三种类型各一根长 30m、内径 0.25mm、膜厚 0.12μm 的色谱柱

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

Enantiomers of C-3 secondary alcohols, 3-hydroxybutanoates, and cyclic 1,3-dithioacetals were separated by chiral GLC using CP-Chirasil-Dex CB and Chiraldex G-TA columns. The former was most successful for analysis of n-alkyl esters of secondary alcohols and the separation depended on the

The enantiomeric excess of chiral reagents used in asymmetric syntheses directly affects the reaction selectivity and product purity. In this work, 84 of the more recently available chiral compounds were evaluated to determine their actual enantiomeric composition. These compounds are
