General description
助留机理:正相和阴离子交换
样品基质相容性:有机或含水溶液
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
Application
Supelclean™ PSA SPE散装填料可以用作固相分散萃取吸附剂,可通过单流进样多换向系统/固体表面荧光光谱法分析苹果和梨中的二苯胺。
