Our Internet site gives in excess of a hundred and fifty webpages of in depth info on our capabilities, analytical procedures, and scenario histories. A printable summary of our abilities is usually offered listed here.
Scientists are working on acquiring new methods for measuring COD that prevail over these troubles. One promising method is using Sophisticated oxidation procedures (AOPs), that may oxidize an array of natural compounds without the use of harmful chemicals.
The COD test must be thought of an impartial evaluate of the natural issue in the wastewater sample as opposed to a substitute with the BOD test.
The COD test is usually a valuable measure of effluent high quality of the wastewater treatment method plant. It offers A fast, approximate measure of all chemically oxidizable substances and can be used to determine efficiency challenges in cure facilities.
Though colorimetry demands a spectrophotometer or photometer, it provides advantage due to the fact most brands present premixed reagents, so all you must do is operate your samples Using the digestion chemicals and nominal Make contact with.
Take advantage of adaptable measuring devices with various measuring procedures in the sector of non-destructive materials testing. All instruments read more are made for rapidly and accurate measurement.

Common multi-measuring system for parallel coating thickness measurement and content testing with around 8 measuring modules.
What benchmarks, coaching or components do you have to be efficient quickly with your new measuring machine?
COD stands for “Chemical Oxygen Demand” and is a evaluate of the amount of oxygen necessary to chemically oxidise organic substances in drinking water like ammonia or nitrate, in apps including lakes, rivers or wastewater which have been contaminated by domestic or industrial squander.
As described before, COD actions organic make any difference by utilizing a chemical oxidant. It’s significant that a solid plenty of oxidant is utilized to react with nearly all organic and natural product from the sample.
We offer many test solutions for product testing. The bottom substance plus the coating materials in the test part determine which measuring technique is appropriate for your application.
Mercury-free reagents: Most COD vials read more comprise mercury sulfate to get rid of chloride interferences, which would normally develop a falsely large COD value. COD-absolutely free vials usually do not contain mercury, that makes them more susceptible to chloride interferences, but enormously decrease the protection and environmental pitfalls of managing mercury.
Our products and services for materials Assessment range between nanomaterials by floor therapies, skinny films and coatings, to bulk products.
