Description

technical field [0001] The invention relates to the technical field of arc discharge, in particular to an arc discharge light source. Background technique [0002] Arc discharge is a phenomenon in which two electrodes are kept electrically conductive by gaseous charged particles, such as electrons or ions, under a certain voltage. It is the strongest self-sustaining discharge among gas discharges. Arc discharge can excite the sample to generate spectrum. For example, arc discharge mainly emits atomic spectral lines, which is a commonly used excitation light source for emission spectrum analysis. Among them, the oil spectrometer can use arc discharge excitation light source. However, there are few studies on the arc discharge excitation light source used in the oil spectrometer in the prior art, and the excitation light source used in other fields is not suitable for direct application in the oil spectrometer. Contents of the invention [0003] In view of this, an embodime...
