TN62: Reducing Carbonate Interference in Anion Determinations with the Carbonate Removal Device (CRD): Perchlorate in Drinking Water
Description
Carbonate can interfere with accurate quantification of adjoining anions, such as perchlorate and sulfate. Perchlorate is a highly regulated contaminate because of the health risks to pregnant women, prenatal and developing children. Here we show the efficient removal of the carbonate peak from a synthetic high ionic water sample using the Dionex CRD 200 device. In this example, the high ionic water matrix contains: 5 ppb perchlorate in a Sunnyvale drinking water sample.| Market: | Environmental |
