Problems solved by technology
[0003] Existing X-ray fluorescence spectrometers are usually designed with a sample stage, and the samples to be inspected are placed on the stage for detection. They can only detect small samples such as electronic components, soil, ore samples, and small metal samples. Difficult to apply to the determination and analysis of low-level elements in items with large volume and complex structure, such as parcels, luggage, etc.
