Where, λ is the wavelength spectrum analysis; d is the crystal lattice spacing; θ is the diffraction angle; n is the diffraction order. Use goniometer can measure the diffraction angle spectrum analysis, the use of the formula to calculate the corresponding wavelength element being analyzed Hua Wei UX-300ROHS instrument to obtain the characteristic information measured elements. Energy dispersive ray fluorescence spectrometer is used energy detector Hua Wei ROHS detector, by measuring the amount of charge collected by the detector, direct access to feature-ray energy emitted measured elements: Q = kE where, K is the incident ray photons the corresponding amount of charge Q is generated by the detector;; k for different types of energy the energy response of the detector parameters. The amount of charge is proportional to the incident ray energy Hua Wei UX-230, so that the measured elements characteristic information obtained by measuring the amount of charge. Measurement time: 60-200 sec temperature range is 15 ℃ to 30 ℃ Power: AC 220V ± 5V (AC purified regulated power supply) Three-dimensional design freedom large sample chamber, the sample chamber size: Φ450 x 90 mm at one time simultaneous analysis of 24 elements weight: 110 kg4 performance editing semiconductor silicon electric refrigeration system, instead of liquid nitrogen cooling automatic filter selection Hua Wei UX-230 | Hua Wei | Shengding instrument provided by the Dongguan City Ding Sheng Precision Instrument Company.
