Description générale
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.

Caractéristiques et avantages
- Excellent sample prep performance at a lower price
- Amenable to generic methodology - save time, money, and headache during method development
- Greater capacity allows for smaller bed weights = smaller elution volumes = time savings in sample processing
- Resistance to overdrying allows for more robust methdology
- Low UV and MS extractables for lower background and greater sensitivity
- Stringent production and QC guidelines offer greater lot-to-lot, tube-to-tube, and well-to-well consistency for improved accuracy and precision

SPE retention mechanism in this case is based on the electrostatic attraction of charged functional groups of the analyte(s) to oppositely charged functional groups on the sorbent.
Protocoles
To optimize hydrolysis using β-glucuronidase, factors such as incubation time, temperature, hydrolysis pH, enzyme source, and enzyme concentration must be evaluated for each glucuronide metabolite to be analyzed.
Retention occurs through polar interaction between the sorbent and analytes. Typical sample matrices that can be employed in normal-phase SPE include hydrocarbon or fatty oils diluted in a solvent like hexane, isooctane, chlorinated solvent, THF, diethyl ether, or ethyl acetate.
