General description
球形炭颗粒(炭分子筛)
保留机制: 反相
样品基质相容性: 水溶液(饮用水、地面、废水)
保留机制: 反相
样品基质相容性: 水溶液(饮用水、地面、废水)
- 开发和设计用于从饮用水和地下水等含水样品中固相萃取高极性化合物
- 在反相条件下使用时,对非极性和极性基质中有机极性和非极性化合物的极端亲和力
- 与传统石墨化炭黑 (GCB) 不同(例如,Supelclean ENVI-Carb),其呈颗粒状且易碎,ENVI-Carb Plus 由强高表区域球形颗粒组成。
- 高极性化合物回收示例(≥70%),包括(但不限于)乙酰甲胺磷 (logP =-0.85)、苯酚 (logP = 1.51)、1,4-二氧六环 (logP =-0.27) 和氨基乙二酰 (logP =-1.2)。
- 与 SPE 真空歧管、公鲁尔接头(目录号:25064-U),母鲁尔接头(目录号:21015),需要空的 SPE 管,但不随附。

Small polar organic pollutants have been discovered to be great threats to the groundwater' as they often are highly mobile and persistent in the environment. 1,2,4-Triazole and N,N-dimethylsulfamide, two well-known examples of small polar compounds, are frequent pollutants of upper

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.
