YSHM-200F Portable grain heavy metal detector copper cadmium lead zinc detector
Application field
Emergency monitoring of heavy metal contamination in food (such as "pot rice" emergency monitoring);
Grain Bureau agricultural product quality control;
Industrial and commercial department food monitoring and analysis;
Monitoring and analysis of heavy metals in aquatic products;
Application case
Five rice samples were obtained from a grain field. YSHM-200F was used for rapid sample processing and determination, and the measurement method was compared with an imported manufacturer's XOS single wavelength dispersive X-ray fluorescence instrument (Cd lower quantification limit 0.05ppm). The test results are as follows:
