A polymeric sorbent that can be employed in the extraction and purification of
polar and nonpolar molecules from a complex media (e.g. pharmaceuticals from biological
matrices) by solid phase extraction (SPE). The sorbent exhibits a strong capacity
for the retention of polar molecules and can facilitate the recovery of compounds
possessing a range of polarities while furnishing clean extracts showing low ion
suppression. The polymer is wettable and remains wetted over long periods of time.
