Chemical Oxygen Demand (COD) can be an analytical system which indirectly steps the level of oxygen required to oxidize the organic issue within a water sample. The upper the focus of organic compounds in the sample, the increased the COD measurement will be.
The Spectroquant® Mobile Tests have prefilled sixteen mm round cells and all of the demanded reagents to conduct the Investigation according to the instruction leaflet delivered.
I instructed her terrific dilemma! It had been honestly The 1st time I have been asked it, which I envision is for the reason that a lot of people's eyes glaze above when they hear Individuals phrases.
