The K-7350S COD Vials Kit by CHEMetrics is engineered to provide accurate measurements of Chemical Oxygen Demand (COD) in water, specifically targeting the range of 0-150 ppm. COD determination is crucial in both municipal and industrial laboratories for assessing the level of organic contamination in wastewater. This contamination is quantified by measuring the oxygen required to oxidize the organic matter in the sample.
Dichromate Reactor Digestion Method: Reliable and Efficient
CHEMetrics has refined the dichromate reactor digestion method to ensure fast, easy, and safe COD determinations across low, mid, and high-range levels in wastewater. Two main methods are offered:
- USEPA-Accepted Method: This method incorporates mercuric sulfate in the reagent to effectively eliminate chloride interferences. It is widely accepted for regulatory reporting.
- Mercury-Free Method: Ideal for situations where chloride interference is not a concern, and USEPA reporting is not required.
Both methods ensure precise results and are tailored to meet diverse testing needs.
Simple and Safe COD Determination
CHEMetrics’ vials are designed for convenience and safety. Each leakproof vial contains premeasured amounts of sulfuric acid and potassium dichromate. The process for determining COD is straightforward:
- Prepare the Vial: Remove the Teflon-lined screw cap from the vial.
- Add Sample: Introduce the water sample into the vial.
- Seal the Vial: Replace the screw cap securely.
- Digest the Sample: Heat the vial for two hours at 150°C in a standard digestor block.
- Measure the Results: Once digestion is complete, use any photometer that accepts 16-mm diameter cells to read the results. CHEMetrics’ vials are compatible with the V-2000 multi-analyte photometer, single analyte COD photometers, and many Hach spectrophotometers, utilizing existing Hach COD methods and calibrations. For other spectrophotometers, a generic calibration equation is provided.
This method ensures accurate and reproducible results, simplifying the overall testing process.
