Porous Polymer Supports

Porapak

 

Porapak consists of cross linked polysyrene beads and give outstanding seperations of volatile compunds, notably sharp, symmetrical retention times are found for water, alcohols and glycols. All Porapaks feature no bleeding of column, no adsorbtion of polar compounds and stability at high temperatures.
