Common use cod digestion vials with high range

The HI93754F-25 COD kit contains 25 ready-to-use vials containing pre-measured reagents. These high quality reagents follow the ISO approved method 15705 for determination of COD. In this method, a heated digestion is required to oxidize organic matter in the sample.

2010/10/14 · Pre-prepared low-range (3-50 ppm) or high-range (20-1500 ppm) vials are selected for the COD test based on expected results. Both ranges can be used if expected results are unknown. One vial is marked as a “blank,” and three or four vials are marked with known standard levels.

The chemical oxygen demand value will be read in mg/L for both total COD (tCOD) and soluble COD (sCOD). For samples with a concentration of 0 to 150 mg/L, use the low range COD vials. For higher

Government regulation Many governments impose strict regulations regarding the maximum chemical oxygen demand allowed in waste water before they can be returned to the environment. For example, in Switzerland, a maximum oxygen demand between 200 and 1000 mg/L must be reached before waste water or industrial water can be returned to the environment .

The HI93754C-25 COD kit contains 25 ready-to-use vials containing pre-measured reagents. These high quality reagents follow follow an adaptation of the dichromate method for COD determination. In this method, a heated digestion is required to oxidize organic matter in the sample. During the digestion, hexavalent chromium in the reagent is

Low range COD (<150 ppm) analysis measures the decrease in the oxidant, Cr2O7 2-. High range COD (<1,500 ppm) analysis measures the increase in Cr3+. A spectrophotometer sends the correct wavelength through the sample cell to a detector that

Request quotation. The HI93754B-25 COD kit contains 25 ready-to-use vials containing pre-measured reagents. These high-quality reagents follow the EPA approved method 410.4. In this method, heated digestion is required to oxidize organic matter in the sample. During the digestion, hexavalent chromium in the reagent is reduced to trivalent chromium.
