一般描述

Porapak多孔聚合物是一种球形珠粒，具有一致的粒径、孔隙率和表面积，有助于确保分析的精确度和准确度。

有关我们任何吸附剂的更多信息，请访问 sigma-aldrich.com/adsorbents
多孔聚合物是最适合用于分析气体、酸、胺、低碳数和水含量有机物等应用的吸附剂。它们最适用于气相色谱，这些聚合物基本上是聚二乙烯基苯（DVB）的共聚物，其具有多孔的性质，孔径可为中孔到微孔。Porapak™ T是一种多孔聚合物，由二甲基丙烯酸乙二醇酯（EGDMA）组成。此外，发现它与醇，醚和酮中的氧原子表现出强烈的相互作用。

应用

Porapak™ T可用于通过薄层色谱（TLC）和液相色谱（LC）选择性分离芳香烃及其部分氢化衍生物。
