Descrição

Descrição geral

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

Aplicação

Porapak^™ QS treated with 2% phosphoric acid maybe used as column packing for gas chromatographic analysis of volatile fatty acids in rumen fluid.

Nota de rodapé

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