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。

应用


  • Enantioselective gas chromatographic analysis of aqueous samples by on-line derivatisation. Application to enzymatic reactions.: This study explores the use of the Astec CHIRALDEX G-TA Capillary GC Column for enantioselective gas chromatographic analysis. The method involves on-line derivatization, enabling the analysis of aqueous samples and applying this technique to enzymatic reactions. This innovative approach highlights the column′s capability in achieving high selectivity and sensitivity for chiral compounds in complex matrices (Mommers et al., 2008).
