Instrument description:ICP-OES Avio 200 inductively coupled plasma atomic emission spectrometer, mainly composed of five parts: sampling system, radio frequency (RF) generator, spectroscopy system, CCD detector and operating software. It is also equipped with a gas control system and cooling system. After the sample is brought into the atomization system by carrier gas (argon) for atomization, it enters the axial channel of the plasma in the form of aerosol, and is fully evaporated, atomized, ionized and excited in a high temperature and inert atmosphere, and emits the contained The characteristic spectrum of the element. According to the presence or absence of characteristic spectral lines. Identify whether the sample contains a certain element; determine the content of the corresponding element in the sample according to the intensity of the characteristic spectrum, and the detection limit is at the ppm level. It can be used to analyze the content of metal elements and some non-metal elements in water, soil, minerals, food, petroleum, and chemical products.
