Accurate COD Measurement with COD Vials Low Range Part Number K-7355
The COD Vials Low Range Part Number K-7355 – EPA accepted, is specifically designed to measure Chemical Oxygen Demand (COD) in water with a range of 0-150 ppm. COD determination is a crucial process in municipal and industrial laboratories to gauge the overall organic contamination levels in wastewater. This contamination level is quantified by calculating the amount of oxygen needed to oxidise the organic matter present in the sample.
Dichromate Reactor Digestion Method
CHEMetrics provides two dichromate reactor digestion methods for quick, straightforward, and safe determination of COD levels across various ranges in wastewater: the USEPA-accepted Method* and a mercury-free method. The USEPA-accepted method incorporates mercuric sulfate in the reagent to mitigate chloride interference. The mercury-free alternative is suitable when chloride interference is not an issue and USEPA reporting is not mandatory.
Easy-to-Use Leakproof Reagent COD Vials Low Range Part Number K-7355
CHEMetrics’ reagent COD Vials Low Range Part Number K-7355 vials are leakproof and contain premeasured amounts of sulfuric acid and potassium dichromate. To determine COD, the analyst needs to:
1. Remove the Teflon-lined screw cap from the vial.
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 Results
Upon completing 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 needing a new calibration. Additionally, the CHEMetrics™ kit includes a generic calibration equation for use with other spectrophotometers.
EPA accepted (150 vials) 0-150mg/L. (LR)
COD Vials Low Range Part Number K-7355 can be used as a replacement for Hach vials. Further info is available on request.
