General description
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。
Application
- 通过在线衍生化对水样进行对映选择性气相色谱分析。酶反应的应用: 本研究探讨了Astec CHIRALDEX G-TA毛细管气相色谱柱在对映选择性气相色谱分析中的应用。该方法涉及在线衍生化，能够分析水样并将该技术应用于酶促反应。这种创新的方法突出了该柱有能力在复杂基质中实现手性化合物的高选择性和灵敏度（Mommers et al., 2008）。
Features and Benefits
温度限制：
- -10 °C 至 180 °C 等温和程序的
