Porapak column packing materials consist of spherical polymer beads. These packings are chemically and physically stable with consistent particle size, porosity and surface area.

Versatility for Special Applications
Porapack packing is a versatile polymer material available in differenct chemistries whihc increase in polarity and vary in retention properties for the efficient analysis of many compounds. These packing materials offer many advantages:
• Polar molecules elute quickly making analysis simple and straightforward
• No liquid phase eliminates stationary phase bleed
• No surface hydroxl groups eliminates tailig of highly polar molecules or of large sample loads for trace analysis and preparative GC
• Stable baselines at high temperatures
