WebA mass spectrum is simply the m/z ratios of the ions present in a sample plotted against their intensities. Each peak in a mass spectrum shows a component of unique m/z in the sample, and heights of the peaks connote the relative abundance of the various components in the sample. Example of a mass spectrum WebA mass spectrometer produces charged particles (ions) from the chemical substances that are to be analyzed. The electric charge is like a “handle” that allows the electric and magnetic fields to move the charged particles around so that we can measure the mass ("weight") 1 of the charged particles. cigna and blue cross blue shield
