5220 CHEMICAL OXYGEN DEMAND (COD)* 5220 A. Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled con-ditions. The quantity of oxidant consumed is expressed in terms of
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
The VialTweeter is powered by the ultrasonic processor UIS250v (250 watts, 24kHz). This compact and reliable unit is easy to set-up and operate. As the ultrasonic generator is tuned to the frequency of the sonotrode automatically, there is no manual frequency tuning required. For a good transmission of the ultrasonic vibrations to the
Hach’s USEPA-approved dichromate COD Method is the most widely used chemical oxygen demand method in the world for NPDES reporting and for easy process monitoring. Chemical Oxygen Demand 8000: Low Range and High Range 10211: Ultra-low Range 10212: Ultra-high Range 10067: Mercury-free Manganese III Digestion Method with chloride removal 10067: Mercury free Manganese III
26/5/2020 · There are many quality parameters used to characterize water quality that can be grouped into physical, chemical, and biological properties. For the 2015 sampling campaign, which was for a bulk examination with 233 samples, we reduced water quality parameters measured to save analysis cost.
