This product can expose you to chemicals including chromium, which is known to the State of California to cause cancer and birth defects or other reproductive harm. A generic calibration table is included within the CHEMetrics kit for use with other spectrophotometers. Built-in Hach COD methods and calibrations can be used without the need for a new calibration. CHEMetrics' COD vials can be directly used in the V-2000 multi-analyte photometer, CHEMetrics' single-analyte COD photometers, as well as in Hach1 spectrophotometers. Once digestion is completed, results are obtained using any photometer that accepts 16-mm diameter cells. The vial is then heated for two hours at 150☌ in a standard digestor block.

To perform the COD determination, the analyst simply removes the PTFE-lined screw cap from the vial, adds sample to the vial, and replaces the cap.

CHEMetrics' leakproof reagent vials contain pre-measured solutions of sulfuric acid and potassium dichromate. The more readily disposable mercury-free product line is applicable when chloride interference is not a concern and USEPA reporting is not required. The products using the USEPA-approved method contain mercuric sulfate in the reagent to eliminate chloride interferences. Chemetrics offers two dichromate reactor digestion methods for fast, easy, safe determinations of low-, mid-, and high-range COD levels in wastewater: the USEPA-approved method, and a mercury-free method.
