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
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™ R is a porous polymer composed of vinyl pyrollidone mainly suitable for the separation of ethers and esters.

应用

Porapak™ R with Amberlite™ XAD-4 maybe useful for chromatographic sampling of polar and nonpolar low-volatility compounds.

  7. What is the maximum temperature for this packing?

    The maximum temperature for this packing is 250 °C.

  8. What does the 80/100 stand for in the product description?

    The 80/100 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 80 refers to a diameter of 177 microns and 100 refers to a diameter of 149 microns.  Therefore; the particles in this product with 80/100 will range between 149 microns and 177 microns.

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

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