Atomic Emission Spectrometry(AES）refers to an analytical method that uses the spectrum formed by the radiation lines emitted by excited atoms to compare with the standard spectrum and identify what substances are contained in the substance.

PJ-10 is a high-performance spectroscopic instrument developed based on the principle of atomic emission spectroscopy for direct analysis of solid samples. It is equipped with a self-developed high-energy density plasma excitation source. The high-temperature plasma directly acts on the surface of the solid sample. The elements in the sample are vaporized and excited at high temperatures, and corresponding characteristic spectral lines are generated during the process of de excitation back to the ground state. The composition and content of the elements in the sample are analyzed through characteristic spectral lines.
