Product Name: RIGAKU 3640Purpose: It is a wavelength dispersive X-ray fluorescence spectrometer, suitable for metallurgy, ore, environmental monitoring and other fields. It is used for qualitative and quantitative analysis of multiple elements in solid, powder and liquid samples, supporting raw material screening and quality control in production processes.Technical Principle: Based on X-ray fluorescence technology, X-rays excite samples to produce characteristic fluorescence. After being dispersed by crystals, the detector receives fluorescence signals of specific wavelengths, and the types and contents of elements are determined with calibration data.Performance: Detectable element range from boron (B) to uranium (U); X-ray tube power 400W; detection limit as low as 0.0001%; equipped with automatic sample exchanger, single analysis time 3-10 minutes, long-term stability RSD≤0.1%.
