1.Instrument Introduction
DR-2020Multi parameter heavy metal online analyzer is a specialized instrument for automatic monitoring of trace heavy metals in water, which uses electrochemical technologyYang in the middlethe utmost pointThe principle of dissolution voltammetry can continuously monitor the content of heavy metals such as cadmium, lead, copper, and zinc in water, with a determination limit of up to μ mg/LLevel.
2.Working principle
Adopting Yangthe utmost pointDissolution voltammetry(ASV)Principle: Firstly, the analytical solution is pre electrolyzed under certain conditions to enrich the analyte in the working electrodethe utmost pointNext, let the solution stand still for a period of time, and then apply a reverse voltage to enrich it in the working electricitythe utmost pointThe test substance is dissolved and analyzed by dissolution voltammetryCurve, calculate the concentration of the heavy metal to be tested.
3. Product Features
