These vials are commonly employed in water laboratories for analyzing wastewater and other moderately polluted water sources using the reactor digestion method.<br \/> Here\u2019s a more detailed breakdown:<br \/> High Range COD Measurement:<br \/> The \u201cHR\u201d in the name signifies that these vials are designed for measuring COD in samples with higher concentrations of organic pollutants, up to 2500 mg\/L.<br \/> Reactor Digestion Method:<br \/> COD analysis using these vials typically involves a reactor digestion method, where the sample is heated with a strong oxidizing agent (like potassium dichromate) in the presence of sulfuric acid and a catalyst (like silver sulfate). This process oxidizes the organic compounds in the water, and the amount of oxidant consumed is measured to determine the COD.<br \/> Applications:<br \/> These vials are suitable for various applications, including:<br \/> Wastewater analysis: Monitoring COD levels in industrial wastewater and municipal sewage to assess pollution and ensure compliance with environmental regulations, according to Hach and Zandaux.<br \/> Industrial water quality assessment: Evaluating the quality of process water and effluent streams in industrial settings.<br \/> Environmental monitoring: Assessing COD levels in surface water bodies like rivers, lakes, and reservoirs, particularly those with moderate pollution levels.<br \/> Pre-prepared Reagents:<br \/> These vials come pre-filled with the necessary reagents, simplifying the testing process and minimizing the handling of hazardous chemicals.<br \/> EPA Approval:<br \/> These vials are approved by the US EPA for wastewater analysis using the Hach Method 8000. <\/p>\n<p>COD Digestion Vials, High Range, pk\/150<\/p>\n<p>COD Digest Vials HR 20-2500mg\/L <\/p>\n<p>It is used in the water laboratories for analysis and research :<\/p>\n<p>For determination of high range Chemical Oxygen Demand (COD) the Reactor Digestion method.<br \/> US EPA approved for wastewater analysis using Hach Method 8000.<br \/> Range: 20 -1500 mg\/L COD.
