HEAVY METAL ELEMENTS ANALYZER IN FOOD

NX-100FA

NX-100FA can be used to rapidly detect heavy metals such as Cadmium (Cd), Lead (Pb), Arsenic (As) and Selenium (Se) in paddy, rice, wheat, corn, beans and other foods as well as their products. Moreover, it can be applied to the storage, circulation and processing of food products at grain depot, food inspection station, food processing enterprise and research institute. NX-100FA can adapt to the special condition of food procurement with ensuring accuracy and stability of test results.

Description

The principle of X-ray fluorescence spectrum analysis is adopted in NX-100FA. The primary X-ray beam, generated by X-ray tube under the excitation of Digital-Control high voltage power, is tailored and restricted to specific spectral by carefully-selected primary filters and optical system to excite sample. The elements measured in sample can generate fluorescent X-ray with characteristic wavelength, which can be captured by high performance FastSDD detector. After that, precise quantification can be finalized by software.
