General description
样品基质相容性：有机溶液或水溶液
- 多点键合的苯磺酸官能团，pKa (< 1.0)
- 反离子为 H+
- 硅胶基体可与强有机溶剂一起使用（不会收缩/溶胀）
- 极好的离子交换容量用于净化组合化学反应的溶液相（0.8 毫当量/克）（从反应副产物和多余试剂中移除目标分子）
- 当从水溶液基质中提取阳离子时，应考虑苯环的存在，它能够提供混合模式作用能力（疏水相互作用）

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.
实验方案
Melamine was extracted from milk using Supelco® Discovery® DSC-SCX SPE tubes. Analysis was performed by HPLC, using an Ascentis® Express HILIC column.
Normal-phase SPE separates analytes based on polar interaction with sorbents in diverse sample matrices.
