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。

化学/物理抗性

温度限制：
  • -10 °C 至 180 °C 等温和程序的

其他说明

We offer a variety of chromatography accessories including analytical syringes
