General description
样品基质相容性：有机或含水溶液
- 聚合键合的乙二胺-N-丙基相，同时含有伯胺和仲胺。
- pKa 为 10.1 和 10.9 的弱阴离子交换剂
- 就选择性而言，与氨丙基固相萃取相 (NH2) 类似，但由于存在仲胺（0.98-1.05 毫当量/克），所以容量更大
- 当进行食品中的多残留杀虫剂分析时，其强亲和性和高容量可用于去除脂肪酸、有机酸和一些极性色素及糖类
- 该产品可降低食品气相色谱分析过程中出现的基质增强效应的影响
- 通过 GC-FID 和 GC-MS 测试其出色的净化效果
- 配体的双齿性质可用于螯合

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