Economical cod digestion vials for water analysis

COD is a defined test; the extent of sample oxidation can be affected by digestion time, reagent strength, and sample COD concentration. COD often is used as a

Description. 16mm Camlab Water COD vials for Chemical Oxygen Demand Analysis. Results displayed as O2 mg/l. Please note a reactor is required for sample digestion. The tube tests are in high-quality glass and the reagent tubes are shipped in special packaging to protect them during transport. All COD tests are available with a set of 25 tubes.

Results are in mg/L COD. 7. If using High Range Plus COD Digestion Reagent Vials, multiply the result by 10. For most accurate results with samples near 1500 or 15,000 mg/L COD, repeat the analysis with a diluted sample. DISCUSSION Compare the COD

5220 CHEMICAL OXYGEN DEMAND (COD) Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties, the dichromate ion (Cr 2 O 72−) is the specified

Scope and application: For water and wastewater. Digestion is required. 1 Ranges 3 to 150 mg/L COD and 20 to 1500 mg/L COD are USEPA approved for wastewater analyses (Standard Method 5220 D), Federal

20/11/2020 · Nov. 20th, 2020. The COD Test Tube produced by Aijiren is often used for chemical oxygen demand (COD) testing, and COD testing uses a specific oxidant to oxidize the substances (including organics) in the water sample. As the temperature and time decrease, the test requires This method is often widely used as a measure of organic pollutants.

23/7/2019 · The contamination level is determined by measuring the equivalent amount of oxygen required to oxidize organic matter in the sample. CHEMetrics, Inc., offers two methods (USEPA-accepted and mercury-free) for fast, simple, safe determinations of low-, mid-, and high-range COD levels in wastewater—at savings of about 30% versus competitive vials.
