Updated Application for More Sensitive Testing of Toxic Hexavalent Chromium in Drinking Water
In addition, after the United States EPA released its Toxicological Review of Hexavalent Chromium report, the California Office of Environmental Health Hazard Assessment (OEHHA) agency has issued a new Public Health Guideline (PHG) for chromate at 0.02 ppb in drinking water.
Application Update 179: Sensitive Determination of Hexavalent Chromium in Drinking Water from Dionex successfully demonstrates a very sensitive ion chromatography method for determining hexavalent chromium at the proposed California PHG level of 0.02 μg/L. Using the Dionex 2 mm IonPac® AG7 guard and IonPac AS7 analytical columns, the method appropriately reduces the flow rates and reaction coil volume.
