Principle of high-voltage power supply in fluorescence analysis
The principle of the high-voltage power supply in fluorescence analysis is to use an electric field to accelerate electrons. After the electron beam hits the sample, it will excite the atoms or molecules in the sample, causing them to be in an excited state. In the excited state, atoms or molecules will emit fluorescence, the energy of which is related to the energy level difference of the excited state. The intensity of the fluorescence signal is proportional to the number of excited atoms or molecules in the sample.
