[0001] This utility model relates to the field of plasma spectrometer technology, specifically a liquid-cooled plasma spectrometer. Background Technology

[0002] Plasma spectrometer is an analytical instrument used to determine the elemental content in various substances. Also known as inductively coupled plasma emission spectrometer, it is a spectroscopic analysis technique that uses plasma as an excitation source. It can perform qualitative and quantitative analysis of major, trace, and ultra-trace elements in samples. This instrument is characterized by high efficiency, strong anti-interference ability, wide testing range, fast analysis speed, and low detection limit, and is widely used in rare earth, geology, metallurgy, chemical industry, environmental protection and other fields.
