Title
(EN) Oxidant sensor
Abstract
(EN)

A microfluidic device for measuring an amount of an oxidant in a solution is disclosed. The device includes a microfluidic substrate configured to mix a solution sample to be analysed with an indicator dye solution containing an indicator dye under conditions suitable for some of the indicator dye to react with any oxidant in the solution to produce an oxidant measurement solution having a reduced indicator dye concentration that is indicative of the amount of oxidant in the solution, the microfluidic substrate including an optical reading window through which the reduced indicator dye concentration in the oxidant measurement solution can be measured optically.
