[0002] A direct-reading spectrometer is a commonly used metal element analysis device. Its working principle is that high-voltage discharge between a sample on a spark table and a tungsten electrode excites the sample to generate atomic vapor, and then the composition of metal elements is analyzed.

Although the analysis result can return to a stable state after cooling for a period of time, frequent temperature changes seriously affect the analysis efficiency and accuracy.
