[0002] Inductive coupling usually refers to a commonly used chemical analysis technology, also known as inductively coupled plasma mass spectrometry. This technology vaporizes the sample and puts it into high-temperature plasma, and uses radio frequency electric fields to induce the coupling between the electrons and positive ions in the plasma. The electrons and positive ions in the plasma interact and move, and trigger a chain reaction, thereby generating a large number of multi-ionized high-energy ions. These ions are separated and detected and analyzed by a mass spectrometer. Since the inductively coupled plasma mass spectrometer is in the air for a long time, it is easy to cause dust accumulation, so a dust cover is required to block the dust;
