一般說明
样品基质相容性：有机溶液或水溶液
- 多点键合的乙二胺三乙酸相，pKa 为 4.8
- 反离子为 Na+
- 离子交换能力为 ~0.15 毫当量/克。

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.

條款
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.
