NX-300 Food Heavy Metal Detector Introduction: The NX-300 food heavy metal detector utilizes the principle of X-ray fluorescence spectroscopy analysis. The X-ray tube generates a primary X-ray beam under the excitation of a digitally controlled high-voltage power supply. This beam is carefully tailored and constrained by a specially selected filter and optical path collimation system to form X-rays with a specific spectral distribution, which are then incident on the sample. The elements to be tested in the food sample generate fluorescent X-rays with characteristic wavelengths under the excitation of high-energy X-rays, which are received by a high-performance FastSDD detector. After software processing, precise quantification is achieved. The NX-300 food heavy metal detector from NCS can quickly detect heavy metal elements such as cadmium (Cd), lead (Pb), arsenic (As), chromium (Cr), mercury (Hg), as well as beneficial element selenium (Se) in grains and their finished products, including rice, polished rice, brown rice, wheat, corn, and beans. It can be applied in grain depots, grain inspection stations, food processing enterprises, research institutes, and other links related to the storage, circulation, and processing of grain and oil products. It adapts to the environmental conditions of grain acquisition sites and ensures accurate and stable test results. Features: 1. Without pre-treatment, the food heavy metal detector can directly test powdered or granular food samples; 2.
