Mass Spectrometry (MS)
Mass spectrometry is an analytical method that ionizes the substance to be tested, separates ions by their mass-to-charge ratio (m/z), and measures the intensity of various ion spectral peaks to achieve analysis. Mass is one of the inherent characteristics of matter, and different substances have distinct mass spectra (mass spectra). Utilizing this property, qualitative analysis can be performed, including molecular mass and related structural information.
