Part 3. X-ray fluorescence spectrometry quantitative screening
[Safety Tips]. X-ray fluorescence spectroscopy uses radioactive radiation that is dangerous to the human body, so the instrument must be used when using the instrument.
The manufacturer’s stated and locally specified safety instructions, and the personnel using the equipment are required to perform pre-board safety training and regular safety.

3 Method summary
X-ray fluorescence spectrometer consists of X-ray tube, spectroscopic crystal, detector, amplifier, pulse height analyzer, timer, scaler, count rate
It consists of a recorder and a microprocessor. The primary X-ray emitted by the X-ray tube is incident on the sample, and the sample element is excited to emit fluorescence.
X-rays, together with the scattered rays of the original X-rays, are projected into the surface of the crystal in parallel by a collimator (soller slit), according to Bra
The grating conditions are diffracted, and the diffracted X-rays, together with the crystal scattering lines, enter the detector through a secondary collimator (called the detector collimator).
Photoelectric conversion converts photons that are not directly measurable into electrical signal pulses that can be measured. Detector output pulse through amplifier
After the amplification and the amplitude of the pulse height analyzer are discriminated, the data can be processed by the computer and the result can be output.
The detection limit of X-ray fluorescence spectrometer must meet the requirements of quantitative screening of lead, mercury, chromium, cadmium and bromine in electrical and electronic products.
