一般說明
样品基质相容性：有机或含水溶液
- 含 Supelclean ENVI-Carb（上层）和 PSA（下层）固相萃取吸附剂（使用 PE 筛板隔开）的双层固相萃取管
- 用于在进行食品（如农产品、肉类等）中多种残留农药分析时实现最优的净化效果。
- ENVI-carb 对于极性分子具有强亲和性，并且可以分离/去除食品和天然产品中普遍存在的色素（例如叶绿素和胡萝卜素）

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.

Reversed-phase interaction will retain most molecules with hydrophobic character; it is very useful for extracting analytes that are very diverse in structure within the same sample.

实验方案
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.
