![]() ![]() In a typical MS procedure, a sample, which may be solid, liquid, or gaseous, is ionized, for example by bombarding it with a beam of electrons. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical identity or structure of molecules and other chemical compounds. ![]() Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.Ī mass spectrum is a type of plot of the ion signal as a function of the mass-to-charge ratio. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry ( MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. Analytical technique based on determining mass to charge ratio of ions
