General description
毛细管GC柱也称为开口管柱。载气流过中心孔，并且在整个柱长上不受限制。
Supelco α-DEX 120 柱包含嵌入中极性固定相的全甲基化 α-环糊精，对小分子对映异构体的分离具有极高的选择性。还建议用于分离位置异构体（酚、二甲苯等）。
Application
α-DEX™120用于气相色谱柱中，用于研究在存在对映体纯配体的情况下，将催化对映选择性二乙基锌添加到a-取代的醛中的实验。它它也用于手性色谱柱durin GC分析，用于研究脂肪酶和芳族酸酐对脂肪酶介导的甘油脱对称的实验。
Features and Benefits
温度限制：
- 30 °C至230 °C
Other Notes
我们提供各种色谱配件，包括 分析注射器
