Precise COD Measurement with COD Vials High Range Part Number K-7365

The COD Vials High Range Part Number K-7365 – EPA accepted, is expertly crafted to measure Chemical Oxygen Demand (COD) in water, with a range of 0-1,500 ppm. Widely used in municipal and industrial labs, COD determination helps gauge the organic contamination levels in wastewater by calculating the oxygen needed to oxidise organic matter in the sample.

The COD Vials High Range Part Number K-7365 is packaged in a cardboard box and includes 150 vials, sufficient for up to 149 tests, along with an instruction manual.

All COD kits require a Digestor Block and either the V-2000 Photometer, an A-7325 COD Photometer, or a spectrophotometer that can accommodate a 16 mm round cell. Photometers are sold separately. Please note that CHEMetrics no longer supplies a Digestor Block. For recommendations, contact vanessa@pisci.co.za.

Each series of tests requires a fresh reagent ampoule blank, so the number of tests that can be performed with each kit may vary.

Dichromate Reactor Digestion Method

CHEMetrics offers two efficient dichromate reactor digestion methods for determining COD levels across low, mid, and high ranges: the USEPA-accepted Method* and a mercury-free method. The USEPA-accepted method contains mercuric sulfate to eliminate chloride interference, while the mercury-free option is suitable when chloride interference is not a concern and USEPA reporting is not required.

User-Friendly Leakproof Reagent Vials

CHEMetrics’ reagent vials are leakproof and premeasured with sulfuric acid and potassium dichromate. To conduct COD determination:
1. Remove the Teflon-lined screw cap.
2. Add the sample to the vial.
3. Replace the cap and heat the vial at 150°C in a standard digestor block for two hours.

Photometer Compatibility and Accurate Results

After digestion, results can be obtained using any photometer that accepts 16-mm diameter cells. CHEMetrics COD vials are compatible with the V-2000 multi-analyte photometer, CHEMetrics’ single analyte COD photometers, and numerous Hach1 spectrophotometers. Built-in Hach COD methods and calibrations can be utilised without new calibration. A generic calibration equation is included in the CHEMetrics™ kit for other spectrophotometers.

EPA accepted (150 vials) 0-1500mg/L.  (HR)

K-7365 COD Vials can be used as a replacement for Hach vials. Further info is available on request.

What is Chemical Oxygen Demand (COD)?

Chemical Oxygen Demand (COD) is a wastewater parameter that measures the amount of a specified oxidant after it reacts with organic matter under controlled conditions. A COD test typically involves digestion of a water sample in a sealed vial with potassium dichromate and sulfuric acid at 150^oC for 2 hours.

Why Test for COD?

Measuring COD is essential for:

1. Assessing Water Pollution: COD tests estimate pollution levels in water entering and exiting wastewater treatment plants and industrial facilities.
2. Regulatory Compliance: In the United States, the Clean Water Act (CWA) mandates treatment facilities to comply with pollutant release targets set by the National Pollutant Discharge Elimination System (NPDES).
3. Optimising Energy Use: COD levels help wastewater engineers determine the oxygen required for treatment, influencing aeration equipment power consumption and allowing for better energy management.
