Current situation of heavy metal pollution in grain

For a long time, heavy metal pollution has been one of the main reasons affecting the quality and safety of Food in China. According to statistics, heavy metal pollution leads to more than 10 million tons of grain production in China every year, and more than 1,200 tons of grain is polluted by heavy metals every year, resulting in a cumulative economic loss of 20 billion yuan.

Heavy metal pollution in food most from the contamination of food and raw materials, because of the influence of the natural geographical environment, soil pollution, or to increase the economic benefit and use of pesticides, veterinary drugs, rich in heavy metals lead to constant enrichment of heavy metals in food raw materials in the growth process, heavy metals can accumulate in the body, after reaching a certain threshold, all kinds of biochemical reaction began to destroy the human body, Cause disease.

Product introduction

At present, the detection of heavy metals mainly exist in the complicated sample preparation, instrumentation is not convenient, real-time detection time, not easily problem such as field measurement, therefore, high sensitivity, low cost, portable, fast field testing equipment, to develop and implement food sources of heavy metal pollution control and supervision assessment is of great significance.

YANG 700F food heavy metal rapid detector is an XRF analytical instrument specially launched in the field of food security, used for rapid detection of cadmium, lead, mercury and other heavy metal elements in food. It integrates a number of high-end technologies, such as LANScientific XRF research and development technology for many years, crystal grating spectroscopy technology and basic parameter method, with the advantages of small and portable, simple operation, fast and accurate, can quickly improve the efficiency of on-site detection, escort for food security.

The product principle

The X-ray tube emission spectrum is composed of continuous lines and characteristic lines. The fully focused hyperboloid curved crystal only diffracts high intensity characteristic X-rays in the X-ray tube emission spectrum, so that the X-ray incident to the sample has good monochromism. So sample from exit X-ray in addition to the elements in the samples are produced by fluorescence X-ray and monochrome outside of Rayleigh scattering and the Compton scattering of the incident ray scattering background, there is no continuous to ensure element under test characteristic line has very low background interference, are elements of the fluorescence X-ray detection with the detector, high resolution and high sensitivity test results are obtained.
