####MAGENTO-BREADCRUMBS####

Porapak ist ein poröses Polymermaterial, welches in der Gaschromatographie eingesetzt wird. Das Material ist neben dem Bulk auch in bereits gepackten Säulen verfügbar. Durch die poröse Struktur, kann dieses Material für die Analyse von flüchtigen Verbindungen und leicht siedenden Lösungsmittel verwendet werden.
