ABSTRACT:
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.
