General description
样品基质相容性：有机或含水溶液
- 含 Supelclean ENVI-Carb（上层）和 LC-NH2（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）
- Supelclean LC-NH2 为氨丙基相，可保留食品基质中普遍存在的脂肪酸、有机酸以及一些极性色素和糖类

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
Normal-phase SPE separates analytes based on polar interaction with sorbents in diverse sample matrices.
