This meter is one of the most versatile photometers in the market, offering 15 measurement methods for different parameters including COD using ready-made liquid or powder reagents. The HI83224 has many advanced

Chemical oxygen demand. In environmental chemistry, the chemical oxygen demand ( COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre ( mg / L ).

Pre-filled with COD reagents, these digestion vials come in either EPA-approved or mercury-free versions for low-, standard-, and ultra-high-range analysis. Each lot is tested to ensure superior quality from the cap and vial to the chemical contents. Glass vials are 16 mm x 100 mm to work with your existing COD reactor and spectrophotometer.

2. Properly label enough prepared COD vials (without mercury for non-regulatory samples) for all samples and standards to be digested. 3. Turn on your COD reactor and ensure it is set to 150°C. 4. Homogenize your sample by mixing or shaking. Aliquot 2 mL of sample or standard into each vial and replace the cap.

Oct 14, 2010 · Thus, COD vials are considered hazardous waste and must be handled and disposed of in an approved manner. Do Not Dispose of COD Vial Contents Down the Drain! Most pre-prepared COD vial vendors will have a return policy for used COD vials so that used vials can be returned to the vendor sealed in the original containers for proper disposal.

May 20, 2021 · The EPA does not allow a modification of the reagents used for reporting purposes. You must use all specified reagents in the COD vial. There are further scientific grounds for keeping your vials consistent with one another. The presence or absence of different ions in solution will have an effect on the optical density of the solution.

Gel-clot Formulation. Pyrotell® lysate was the first LAL gel-clot reagent licensed by the US FDA. It is easy to use and is available in both economical multi-test vials and convenient Single Test Vials (STV's). Pyrotell® lysate is a robust reagent, producing firm, easily read clots and is resistant to interfering substances.

These COD vials are premixed and ready to use. There are several types of reagents available commercially: EPA-compliant reagents: These vials comply with EPA method 410.4 and Standard Methods 5220D. These reagents use the formulation for this method, which contains mercury sulfate, potassium dichromate, and sulfuric acid.

Also, add 1.5 ML of potassium dichromate reagent (digestion solution, to each of the three COD vials). Add 3.5 MI, of sulphuric acid regent (catalyst solution in the same manner). Cap the tubes tightly. Switch on the COD Digester and fix the temperature at 150°C and set the time at 2 hrs. Place the COD vials into a block digester at 150°C and
