COD Digest Vials LR 3-150mg\/L<\/p>\n
COD Digest Vials HR 20-2500mg\/L are used to determine the Chemical Oxygen Demand (COD) in water samples, specifically in the high range of 20 to 2500 mg\/L. These vials are commonly employed in water laboratories for analyzing wastewater and other moderately polluted water sources using the reactor digestion method.
Here\u2019s a more detailed breakdown:<\/p>\n
COD Digest Vials LR 3-150mg\/L<\/p>\n
High Range COD Measurement:
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.
Reactor Digestion Method:
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.
Applications:
These vials are suitable for various applications, including:
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.
Industrial water quality assessment: Evaluating the quality of process water and effluent streams in industrial settings.
Environmental monitoring: Assessing COD levels in surface water bodies like rivers, lakes, and reservoirs, particularly those with moderate pollution levels.
Pre-prepared Reagents:
These vials come pre-filled with the necessary reagents, simplifying the testing process and minimizing the handling of hazardous chemicals.
EPA Approval:
These vials are approved by the US EPA for wastewater analysis using the Hach Method 8000. <\/p>\n
