General description
固相萃取装置使用玻璃瓶或管进行样品收集和浓缩。在这种情况下使用SPE管时,一些吸附剂需要比小型SPE柱更大的解吸体积。
助留机理:反相
样品基质相容性:含水溶液(饮用水、地下水、废水)
样品基质相容性:含水溶液(饮用水、地下水、废水)
- 多点键合,十八烷基 (17%C)(封端)
- 非常适用于从含水环境样品中净化、萃取和浓缩污染物
- 更高的 17%C 含量可得到更大的键合能力以及更高的回收率
- 更高的碳含量也可提供更好的耐极端 pH 条件的性能
- 用于从废物中提取除草剂、杀真菌剂和杀虫剂
Application
Supelclean™ ENVI™-18 SPE管可在SPE中使用,以纯化沿海沉积物样品。它还可用于鉴定阿特拉津的降解产物。
