SampliQ PS-DVB is a highly cross-linked polystyrene-divinylbenzene (PS-DVB)
copolymer. With its high surface area (600 m
2
/g) and high capacity, it is ideal for
the extraction of polar analytes that are not adequately retained on a C18 or C8
sorbent. The nonselective characteristic of this sorbent is useful for screening
applications where a broad range of analytes is to be extracted.
The particle size (75 - 160 μm) makes it ideal for the rapid flow of a large volume
of aqueous environmental sample. The cartridge design has been optimized for
phenol, which typically has low and irreproducible recoveries
