The HI94754A-25 COD kit contains 25 ready-to-use, barcoded vials containing pre-measured reagents. These high quality reagents follow the EPA approved method 410.4. In this method, a heated digestion under acidic conditions is required to allow the oxidizable organic compounds present in the sample to reduce hexavalent chromium to trivalent chromium, causing an orange tint in the sample. The intensity of color is determined by a compatible photometer and the COD concentration is displayed in mg/L (ppm) O2. These reagents are designed to be used with samples that have an expected range of 0 to 150 mg/L (ppm) O2.
Automatic recognition of barcoded samples is an exciting feature when using the HI94754A-25 reagent vials with a barcode compatible photometer. When inserted into the vial holder of the photometer, the sample method and range are automatically identified from the barcode. The barcode has four digits: the first two digits are for parameter identification and the second two digits are for reagent lot ID. Vials for different COD methods can be distinguished by a barcode printed on the vial.
