一般說明
Sample Matrix Compatibility: Aqueous solutions (biological fluids, water)
- Sulfonic acid functionalized hydrophilic modified styrene polymer
- Developed for the extraction of a highly broad range of compounds from aqueous samples
- Retention predominately based on ion-exchange; however, because the phase is hydrophilic modified, it is amenable to polar compounds as well.
