Chromosorb Century polymers

Porous polymers, such as Porapak and the Chromosorb Century Series, are the most widely used adsorbents. Porapak Q and Chromosorb 102 are both styrenedivinylbenzene polymers, have similar separation characteristics and are the most widely used of the porous polymers. The other members of the respective series differ in composition and consequently in selectivity. 

Notes The most commonly used porous polymer sorbent is Tenax-GC, although the Porapakand Chromosorb Century series have also been used Tenax-GC has been used with thermal desorption methods, but can release toluene, benzene, and trichloroethylene residues at higher temperatures in addition to Tenax-GC, XAD 2-8, Porapak-N, and Chromosorbs 101, 102, 103, and 106 have found applications, sometimes in stacked sampling devices (for example, a sorbent column of Tenax-GC — Chromosorb 106 in tandem) Chromosorb 106, a very low polarity polymer, has the lowest retention of water with respect to organic materials and is well suited for use as a backup sorbent... 

Chromosorb Century Series (Johns Manville Corp.) is a range of microporous polymers formed from the co-polymerisation of DVB and styrene, additional vinyl monomers are included to produce a range of co-polymers with varying surface areas and polar characteristics suitable for analysis of a wide range of samples. Table 5.10 summarises the composition of the copolymer, properties and applications.
