Its advantages are sensitive and rapid. Historically, many new elements have been discovered through spectral analysis, such as 铷, 铯, 氦, etc. According to the analysis principle, spectral analysis can be divided into two types: emission spectrum analysis and absorption spectrum analysis; according to the shape of the measured components, it can be divided into atomic spectrum analysis and molecular spectrum analysis. The measured component of the spectral analysis is called the atomic spectrum of the atom, and the molecular component of the measured component is called the molecular spectrum. |
