Terms and definitions defined in GB/T 6379:1, GB/T 13966, GB/T 23942-2009 and JY/T 0567-2020 and the following Applicable to this document: 3:1 Microwave plasma An excited plasma light source formed by coupling microwave energy:

4 Principles of the method

The sample is atomized by the atomization system to form an aerosol, which is carried into the microwave plasma by the carrier gas (nitrogen, helium or argon) and is stable at high temperature:

The atoms or ions of the measured element are fully evaporated, atomized, excited and ionized in the atmosphere: When the atoms or ions of the measured element are excited, the electrons move between different energy levels in the atoms:
