The method of identifying a substance and determining its chemical composition and relative content from the spectrum of a substance is called spectral analysis, which has the advantage of being sensitive and rapid. Historically, many new elements, such as rubidium, cesium and helium, have been discovered by spectral analysis. According to analytical principle, spectral analysis can be divided into two kinds: emission spectrum analysis and absorption spectrum analysis. According to the morphology of tested components, it can be divided into atomic spectrum analysis and molecular spectral analysis.

BEIJING HAMAMATSU PHOTON TECHNIQUE INC. can provide hollow cathode lamp glass shells, PMTs, scintillators and other crystal products for spectral analysis.
