General description
毛细管气相色谱柱又称开管柱。载气流经中心孔,在整个色谱柱长度上不受限制。
β-环糊精-DEX 225 是 β-DEX 325 相,并在 2,3-位使用乙酰基衍生物,而不是更传统的甲基衍生物。β 中手性固定相-DEX 225 色谱柱含有 2,3-二-O-乙酰基-6-0-TBDMS-β-嵌入中间极性相的环糊精。这些色谱柱对小分子的对映体分离提供了独特的选择性:醇类、醛类(例如 2-苯丙醛)、酯类(例如苹果酸甲酯、乳酸甲酯)、风味化合物和酮类。
Features and Benefits
温度限值:
- 30°C 至 230°C
Other Notes
我们提供各种色谱配件,包括 分析注射器
