Red Network Changsha December 10 (go to the hospital for medical examinations, according to an X-ray, immediately see if the lungs are infected. Today, through a magical device to carry out an X-ray perspective of rice, within 3 minutes could find out if heavy metals exceeded rice. this rice is the world's first high-precision heavy metal fast detector, has been put into use in Changsha.

Zhang Wenge, Director of the Bureau of Regulations and Supervision of the Bureau of Quality Supervision and Administration of Changsha City, said that this device was granted national patent in December last year, which was nearly a thousand times faster than the traditional standard method in two days. The rapid detection device for heavy metals was invented by Peng Xinkai, director of the Hunan Food Safety Production Engineering Technology Research Center. It looks like a small microwave oven and is only 55 cm long, 33 cm wide and 44 cm high. For the detection principle of the detector, Peng Xinkai interpreted it vividly as using X-rays to hit a "gun" for rice. This "gun" directly stimulates the heavy metal nuclei of rice and stimulates the energy of M, K, L and other shells. Wave transitions. The instrument analyzes the fluorescence spectrum generated by the transition to determine what kind of heavy metals the test rice contains.

In this year's grain collection work, the detector was used in the Wanmu Experimental Field Base in Xinkang Township, Wangcheng District, Changsha City and the Experimental Field Base in Changsha, Zhuzhou and Xiangtan. According to Peng Xinkai, the National Food Standard Quality Center has been tested and verified in many places this year and it is believed that this method can meet the need for rapid detection of cadmium in rice and will be popularized in the future.
