Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for ICP spectrometers, and in particular relates to a gas switching device and a switching method for ICP spectrometers. Background technique [0002] Inductively coupled plasma spectrometer (ICP spectrometer) is mainly used for the quantitative analysis of metal elements and some non-metal elements in liquid samples (including solid samples that can be converted into solutions by chemical treatment). [0003] The instrument first introduces the sample solution into the plasma torch in the form of aerosol. After the sample is excited and excited, it emits the light of the characteristic wavelength of the contained elements. Received by photoelectric devices and converted into electrical information to be recorded. According to the relationship between the concentration of the tested element in the solution and the intensity of the spectral line, the content of each corresponding eleme...
