一般描述

Porous polymers are the most suitable adsorbent for applications based on the analysis of gases, acids, amines, organics of low carbon number and water. They are best suited for gas chromatography and are basically copolymers of polydivinylbenzene (DVB) which are very porous in nature ranging from mesoporous to microporous. Porapak™ P is a porous polymer composed of styrene and divinylbenzene.
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。

  7. What is the maximum temperature for this packing?

    The maximum temperature for this packing is 250 °C.

  8. What does the 100/120 stand for in the product description?

    The 100/120 refers to the mesh size range of the actual particles.  When working with mesh size: the larger the mesh number, the smaller the diameter of the particle.  In this case 100 refers to a diameter of 149 microns and 120 refers to a diameter of 125 microns.  Therefore; the particles in this product with 100/120 will range between 125 microns and 149 microns.

  9. What is the weight in grams of the 75cc HayeSep® container?

    The weight is approximately 24 grams for each 75cc container.
