Description

General description

Porapak porous polymers are spherical beads with consistent particle size, porosity, and surface area that help to insure analytical precision and accuracy.

For more information about any of our adsorbents, please visit 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.

Application

Porapak QS packed column maybe used for gas-solid chromatographic determination of moisture in lyophilized pharmaceutical products.

Footnote

Porapak QS is a silanized version of Porapak Q to reduce surface adsorption.
