Speciation of Bromine Compounds in Ozonated Drinking Water using Ion Chromatography and Inductively Coupled Plasma Mass Spectrometry
Combining the resolving capability of IC with the detection power of ICP-MS allows fast, easy and reliable analysis of bromine species in drinking waters. Low background and He-KED interference removal permit robust conditions so that sample preparation is virtually eliminated and analysis of the water can be performed from the tap to the vial after simple alkalinization. This method enables robust and reliable speciation of bromine containing species in drinking water, with no salinity-related recovery issues. Thanks to the high sensitivity and completely metal free sample and mobile phase flow paths, the application complies to EPA 321.8 quality control requirements and provides MDLs well below the values necessary for accurate monitoring of water from various sources.

运用EPA方法通过IC-MS / MS分析557种卤乙酸,茅草枯和溴酸盐等农药残留
根据美国环保局的报告,长期饮用含有超过0.06 mg / L HAAs水的癌症风险增加(60μg/ L).1 EPA方法552.1,552.2和552.3用于测定饮用水中所有九种HAAs的含量。这些方法需要进行衍生化和多个提取步骤,然后进行气相色谱(GC) 电子捕获检测(ECD)。
