This short video provides viewers with an overview and short summary of Chemical Oxygen Demand (COD) Reagents & Vials.

Chemical oxygen demand also called COD is widely used as a measurement in wastewater and natural waters. COD is defined as the amount of a specified oxidant that reacts with a sample under controlled conditions and is expressed in mg/l. Traditionally COD has been determined by the open reflux, digestion and titration method, as outlined in Standard Method ASTM D1252-06, Test Method A. However, nowadays the widely used colorimetric sealed reflux, digestion and spectrometry method outlined in Standard Methods ASTM D1252-06, Test Method B offers a convenient alternative.
