Rice Heavy Metal Detector

Product Introduction The Heavy Metal Detector by Voltammetry (Rapid Grain Heavy Metal Tester) is a high-precision electrochemical analysis instrument, specially used for detecting **lead and cadmium** in rice and brown rice. Using disposable triple-electrode strips based on anodic stripping voltammetry, it achieves fast and accurate heavy metal detection. With screen-printed electrodes and simple sample pretreatment, it can rapidly quantify lead and cadmium in rice and brown rice. It supports the development of detection methods for various food samples. Working Principle Voltammetry is an analytical technique based on electrochemical principles. It quantitatively analyzes heavy metal ions in samples by measuring the current and potential generated during electrode reactions. By gradually changing the electrode potential, recording current changes, and analyzing the response curve, the concentration of heavy metals in the sample can be determined. Application Fields Grain and oil testing: grain purchasing and processing enterprises, quality inspection institutions, agricultural departments for detecting heavy metals in rice.
