The hottest rice heavy metal rapid detector to imp

recently, the rice heavy metal rapid detector purchased and distributed by Hunan Provincial Grain Bureau settled in the channel and was officially put into use. At present, it is the season for the purchase and warehousing of mid season rice. The use of the heavy metal rapid detector will greatly improve the monitoring of food quality and safety, effectively prevent the excessive heavy metal grains from flowing into the ration market, and enable people to eat real healthy grains and safe grains

on September 5, the author saw at the testing operation site that professional operators put the rice that has been shelled and broken into powder into a plastic container with a diameter of about 2 cm and placed it in a testing hole above the tester. Cover the top cover of the instrument, set the test time on the electronic screen for 600 seconds, and then the detector will automatically start the scanning program. After about 10 minutes, only wavy patterns appeared in the display window. According to the test report, the test value was 0.036 mg/kg. "The standard requirement is less than or equal to 0.2 mg/kg, and the test result of this sample is qualified." The operator said

it is reported that the working principle of the rice heavy metal rapid detector is like shooting a "gun" to the rice with X-rays, which directly excites the heavy metal nuclei of the rice and excites the transition of shell energy waves such as m, K, l, etc. The instrument conducts corresponding analysis on the fluorescence spectrum generated by the transition, so as to judge what heavy metals are contained in the tested rice, and whether the test results meet the requirements of establishing and perfecting the relevant standards and regulations of major projects; In addition to accurate detection results, this detector also has many advantages, such as faster, pollution-free, zero consumables and so on

it is understood that in the past, rice detection required samples to be sent to the detection center at or above the municipal level. The detection personnel had to soak for more than 8 hours before implementing the relevant detection. The whole process has 11 procedures, which will take two days. This kind of detector is a non-destructive inspection. Some customers will know it when they ask. It is easy to operate and the detection cost is low. The result can be obtained in 10 minutes. Compared with the traditional method, it is nearly a thousand times faster, and there is no need for pretreatment. The light fiber reinforced hydrogel has a lot of potential. It is easy to use pine to complete the monitoring of heavy metal content in rice
