WebCHEMetrics. Bromine, a less volatile compound than chlorine, is used as a sanitizing agent in drinking water systems, swimming pools, and spas. The bromine test method employs the DPD chemistry. Potassium iodide is added to the sample before analysis. Bromine reacts with the iodide to liberate iodine. WebDissipative particle dynamics ( DPD) is an off-lattice mesoscopic simulation technique [1] which involves a set of particles moving in continuous space and discrete time. Particles represent whole molecules or fluid regions, rather than single atoms, and atomistic details are not considered relevant to the processes addressed.
Chlorination Test Kits Chlorine in Water Tests CHEMetrics
WebThe first test measures total or combined chlorine and is performed using DPD plus potassium iodide (KI). The second test measures free chlorine and employs DPD alone. By subtracting the free chlorine result from the total chlorine, an estimate of how much chloramine is in the solution is obtained. WebOur goal was to accurately measure free chlorine without using reagents, membranes, electrolyte, or a waste stream. This self-cleaning and flow-independent sensor can be inserted directly into a pipe or a tank. The NSF61 Certified sensor is unlike any other sensor on the market today.
