Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, and in particular to an inductively coupled plasma emission spectrometer. Background Technology

[0002] Inductively coupled plasma optical emission spectrometry (ICP-OES) is an advanced analytical technique used to determine the concentration of multiple elements, especially suitable for simultaneous multi-element analysis. Its working principle involves introducing the sample into a high-temperature plasma, generated by argon gas excited by a high-frequency electromagnetic field, reaching temperatures of tens of thousands of degrees Celsius. At this high temperature, elements in the sample are excited to high-energy states. When these high-energy atoms or ions return to their ground state, they emit characteristic spectral lines. By detecting the intensity of these characteristic spectral lines, the content of each element in the sample can be quantitatively analyzed. ICP-OES, with its high sensitivity, wide dynamic range, low detection limit, and rapid analytical capabilities, is widely used in environmental science, materials research, and testing services.
