TN62: Reducing Carbonate Interference in Anion Determinations with the Carbonate Removal Device (CRD): 5 ppb Perchlorate in 500 mg/L Carbonate, Chloride, and Sulfate Matrix
| # | Compound Name | Compound Class | RT (min) |
|---|---|---|---|
| 1 | Chloride, Carbonate, Sulfate | Inorganic Anion | 4.00 |
| 2 | Perchlorate | Oxyhalide | 9.50 |
Description
Carbonate can interfere with accurate quantification of adjoining anions, such as sulfate and perchlorate. Perchlorate is a highly regulated contaminant (EPA Method 314) because of the health risks to pregnant women and 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 500 mg/L each of carbonate, sulfate and chloride.| Market: | Environmental |
