cod vials for measuring water quality Aijiren

Chemical oxygen demand (COD) is an indirect measurement of the amount of organic matter in a sample. With this test, you can measure virtually all organic compounds that can be digested by a digestion reagent. COD contrasts with biochemical oxygen demand (BOD), which relies on the use of microorganisms to break down the organic material in the

Carbon Oxygen Demand Testing Products. Products used to measure levels of oxidizable organic compounds within water samples; includes tubes, vials, and reagents designed for COD testing. Useful for determining the quality of wastewater and environmental water samples. Read More.

Kit comes in a cardboard box and contains everything needed to perform up to 149 tests (except distilled water): 150 vials and COD Vials Kit.

Carbon Oxygen Demand Testing Products. Products used to measure levels of oxidizable organic compounds within water samples; includes tubes, vials, and reagents designed for COD testing. Useful for determining the quality of wastewater and environmental water samples. Perform colorimetric testing including fluoride, COD, total nitrogen and

COD Testing Advantages. COD is most suitable for rapid and frequent monitoring of treatment plant efficiency and water quality. This method is more accurate than BOD (with a 5-10% relative standard deviation) and it offers a relatively short analysis time (2-hour digestion time), compared to the 5-day BOD test.

Nov 18, 2020 · As for how COD Vial works, Please follow our article. Water quality COD ammonia nitrogen rapid measuring instrument, can quickly detect a variety of water quality COD and ammonia nitrogen values, integrated with the field of water quality analysis mature technology, so that the entire analysis system more perfect, more simple, faster operation

Automatic Sampling. Water quality data relies on sample integrity. Even the most exacting laboratory analysis lacks compensation for improper sample collection, or physical and chemical alteration of a sample due to inappropriate transport and storage. Correct sampling procedures deliver accurate lab results, a critical component when

Aijiren Technologies recommends to use a grounding cable connected on one side at the Injection Valve, Loop or any other suitable direct metallic contact and the other side at an appropriate grounding point at the LC/MS System. This supplementary grounding measure wi ll support the safety strategy of the LC/MS System manufacturer.
