[0002] Arc discharge is a phenomenon in which two electrodes are maintained conductive by gaseous charged particles, such as electrons or ions, under a certain voltage, exciting the sample to produce a spectrum. Arc discharge mainly emits atomic spectral lines and is a commonly used excitation light source for emission spectroscopy. It is usually divided into DC arc discharge and AC arc discharge. Arc discharge is the strongest self-sustaining discharge in gas discharge. When the power supply provides a large power of electrical energy, the inter-electrode voltage does not need to be too high. A strong current can continue to pass through the gas or metal vapor between the two electrodes, emitting a strong glow and generating high temperature. This is arc discharge. Arc is a common thermal plasma.
