Porapak

Porous Polymer Supports

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