Descripción general
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.

Características y beneficios
- 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

The combination of ion-exchange SPE with the HILIC HPLC separation provides a novel approach for the testing of problematic bath salt compounds.
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.
Protocolos
Separation of 3,4-Methylenedioxypyrovalerone HCl (MDPV) solution, 1.0 mg/mL in methanol (as free base), ampule of 1 mL, certified reference material; Buphedrone hydrochloride solution, 1.0 mg/mL in methanol (as free base), ampule of 1 mL, certified reference material; 3-Fluoromethcathinone hydrochloride solution, 1.0 mg/mL in methanol (as free base), ampule of 1 mL, certified reference material; Butylone hydrochloride solution, 1.0 mg/mL in methanol (as free base), ampule of 1 mL, certified reference material; Ethylone hydrochloride, 1.0 mg/mL in methanol (as free base), ampule of 1 mL, certified reference material; 4-Fluoromethcathinone hydrochloride solution, 1.0 mg/mL in methanol (as free base), ampule of 1 mL, certified reference material; Mephedrone hydrochloride solution, 1.0 mg/mL in methanol (as free base), ampule of 1 mL, certified reference material; Methylone hydrochloride, 1.0 mg/mL in methanol (as free base), ampule of 1 mL, certified reference material; Methedrone hydrochloride solution, 1.0 mg/mL in methanol (as free base), ampule of 1 mL, certified reference material
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.
