What’s working principle of DX3201?

A: Principle: Stream of electrons generated through high voltage flows into the X-ray tube and target material shall generate primary X-rays, which shoot into the sample products being tested after filter and aggregation and generate secondary X-rays, that is X fluorescence we usually refer. After being detected by the detector, X fluorescence is amplified and undergoes data reduction, which is entered the computer. Finally, the computer calculates the results we need.
