Explanation: A mass spectrum measures the masses within a sample. Particles are characterized by their mass to charge ratios (m/z) and relative abundances. This technique basically studies the effect of ionizing energy on molecules and is applied to pure samples as well as complex mixtures. This technique is only possible to perform in the gaseous state.
