Sensitive Determination of Hexavalent Chromium in Drinking Water
14 Apr 2011This application note presents modifications to the existing US EPA Method 218.6 to allow sufficient sensitivity for determining hexavalent chromium (i.e., Cr(VI) as CrO4 2-) at the proposed California PHG level of 0.02 μg/L. This includes the use of an IonPac AG7 guard (2 × 50 mm) and IonPac AS7 analytical (2 × 250 mm) columns while appropriately reducing the flow rates and reaction coil volume.

Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.
