Heavy Metal Rapid Detection Instrument

The Rapid Heavy Metal Detector (Grain Heavy Metal Rapid Tester) is a high-precision electrochemical analysis device specifically designed to detect the levels of lead and cadmium in rice and brown rice. This instrument employs a disposable three-electrode anode stripping voltammetry method to achieve rapid and accurate heavy metal detection. Combined with screen-printed electrode consumables and a simple sample pretreatment process, it enables rapid quantitative detection of lead and cadmium in rice and brown rice. It supports the development of testing methods for various food samples.

Voltammetry is an analytical technique based on electrochemical principles that quantifies heavy metal ions in samples by analyzing the current and potential generated during electrode reactions. By gradually altering the electrode potential, recording current changes, and analyzing the response curve, the concentration of heavy metals in the sample can be determined.

The instrument is used in grain and oil testing by grain procurement and processing enterprises, quality inspection agencies, and agricultural departments to detect heavy metal content in rice.

• High sensitivity: Lower detection limits and higher sensitivity enable trace detection.

• Fast and Simple: Compared to traditional wet chemical methods, it eliminates the need for multiple activation pretreatments, making it quicker to use.

• High Accuracy: A seamless integration of laboratory quantitative analysis and rapid testing.

• Cost-Effective: Its relatively low cost enables widespread application.
