Inductively coupled plasma emission spectrometer, abbreviated as ICP spectrometer, is a type of spectrometer for analyzing elements in liquids.ICP spectrometer can quantitatively analyze the vast majority of elements on the periodic table, including metal elements, alkaline earth metal elements, and high-end ICP spectrometers can also analyze halogens. ICP spectrometer belongs to atomic emission spectrometer, which quantitatively analyzes the emission characteristics of different elements based on the emission intensity of spectral lines. ICP spectrometer can only perform liquid injection, and solid can be quantitatively analyzed after acid dissolution and dilution. Therefore, the adaptability of ICP spectrometer is very wide, and it can be applied to element analysis in water quality, environmental protection, and materials. The detector of early ICP spectrometers was a photomultiplier tube, while most contemporary ICP emission spectrometers belong to CCD full spectrum detectors. The ICP of the photomultiplier tube detector belongs to the sequential scanning type. The spectrometer has a moving mechanism inside, which adjusts the angle of the spectral lines when detecting different elements, so as to scan different elements; The ICP spectrometer with CCD detector does not have a moving mechanism inside. When the composite spectral line passes through the grating, the spectral lines split by the grating will be accepted by the CCD full spectrum detector together, and through full spectrum photoelectric conversion, all spectral lines will be accepted; The analysis speed of ICP spectrometer is very fast, and the detection limit is also very low, with a wide linear range, suitable for quantitative analysis of trace and constant elements. However, the cost of using an ICP spectrometer is relatively high, especially in terms of argon gas consumption. Many customers compare it with an atomic absorption spectrophotometer when purchasing. If the daily analysis volume is not particularly large, an atomic absorption spectrophotometer can be used instead of ICP, which will bring savings to users in terms of purchase and usage costs. ICP spectrometer can only analyze liquids, so it may show its disadvantages when conducting trace element analysis of solid materials. For example, when the element content in solid materials is very low, in order to obtain liquid samples, it is necessary to dilute the solid materials. It is possible that the content of the sample after dilution may not reach the detection limit of ICP. At this time, ICP-MS analysis is needed, and mass spectrometry detectors can further improve the detection limit of the instrument. If customers need to analyze ultra-high purity metals, such as materials with a purity of 9 or more, they need to use GD-MS, which is a glow mass spectrometer. Glow mass spectrometer is used for direct excitation analysis of solids, without the need for liquefaction treatment of materials during the analysis process, which means that no dilution is required for direct analysis. Glow mass spectrometer can perform ultra-low content analysis of impurities in high-purity metals or non metals.
