一般描述
Astec® CHIRALDEX G-TA 是第 1 组 CSP（表面相互作用，复合衍生物）的首选。该阶段已被证明是制药行业最广泛选择的阶段，特别是在临床试验的各个阶段中手性中间体和药物研究的分析。在没有包含机制的情况下发生分离，并且通常比大多数手性固定相更快且更有效。G-TA 也被用于分离母体药物对映体及其代谢物。G-TA 对含氧分析物的选择性最高，如醇、二醇和多元醇，作为游离醇和酰基衍生物；胺类作为酰基衍生物；氨基醇、卤素（Cl> Br> F）、氨基酸、羟基酸、内酯、呋喃和吡喃。它对卤化物也具有高选择性。

Chromatographic enantiomeric separation of amino acids, like proline, is described for chiral GC analysis after derivatization.
相关内容
Amino acids are building blocks of peptides and proteins. Enantiomeric separation of these molecules can be performed through chromatography by chiral stationary phases. This article describes the chiral GC analysis of one amino acid, proline, after achiral derivatization.
In this study we demonstrate the separation of D- and L-carvone enantiomers in samples of caraway seed, dill seed, native spearmint and scotch spearmint essential oils using an Astec CHIRALDEX G-TA capillary GC column.
