Rice Heavy Metal Analyzer

Product Introduction:

The voltammetric heavy metal detector (rice heavy metal detector) is a high-precision electrochemical analysis device designed to detect the content of heavy metals lead and cadmium in rice and brown rice. This instrument achieves rapid and accurate heavy metal detection through one-time three electrode anodic stripping voltammetry. Combined with screen printed electrode consumables and a simple sample pretreatment method, it can achieve rapid quantitative detection of heavy metals lead and cadmium in rice and brown rice.

Working Principle:

Voltammetry is an analytical technique based on electrochemical principles, mainly used to quantitatively analyze heavy metal ions in samples by analyzing the current and potential generated by electrode reactions. By gradually changing the electrode potential, recording the 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 agencies, and agricultural departments test the heavy metal content in rice.

Equipment Advantages:

1. High sensitivity: lower detection limit, higher sensitivity, achieving trace detection;

2. Quick and easy: Compared to traditional wet chemical methods, it does not require multiple activation pretreatments, making it faster to use;

3. High accuracy: organic combination of laboratory quantitative analysis and rapid detection;
