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.
特點和優勢

Separation of S(+)-Amphetamine (dextro-Amphetamine) solution, 1.0 mg/mL in methanol, ampule of 1 mL, certified reference material; R(-)-Amphetamine (levo-Amphetamine), 1.0 mg/mL in methanol, ampule of 1 mL, certified reference material
Shown here is the chiral separation of amphetamine enantiomers under MS-compatible conditions on Astec CHIROBIOTIC® V2 after extraction from urine using Supel™-Select SCX SPE 96-well plates. The highest grade mobile phase solvents and additives were used to supply low background interference and low particulate contaminants for robust, trouble-free operation. Cerilliant CRMs provided reliable identification and quantification.
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.

Optimized sample prep and chiral chromatography methods for the LC/MS analysis of these drug enantiomers in urine
In this study, optimized methods are presented for sample preparation and chiral chromatography for the LC/MS analysis of amphetamine and methamphetamine enantiomers in urine.
LC/MS Analysis of Methamphetamine Enantiomers on Astec® CHIROBIOTIC® V2 in Urine after SPE using Supel™-Select SCX
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.
