Mass spectrometry (MS) is essentially a 'weighing' technique for molecules and/or elements. This is obviously not done using a conventional balance. MS, on the other hand, is based on the motion of a charged particle, called an ion, in an electric or magnetic field. This motion is influenced by the ion's mass to charge ratio (m/z). Because the charge of an electron is known, the mass to charge ratio can be used to calculate the mass of an ion. For a long time, organic chemists employed MS to elucidate the structure of unknown compounds . Later, this novel technique became an essential analytical tool in analytical science for detecting and quantifying the analytes of interest at trace to ultra-trace levels . The MS has proven to be a useful analytical tool for analyzing the kinetics of organic dye degradation .
