Aston developed mass spectra for more than 50 elements. Beynon in 1960 first wrote on the theory of mass spectrometry. Dampster proposed the instrumentation for the mass spectroscopy.

Mass spectrometry is defined as the measurement and interpretation of the positive ions based on their masses. It gives the information about the molecular structure of the organic and inorganic compounds.

PRINCIPLE

The basic principle involved in mass spectroscopy is when the compounds are bombarded with electrons, the compound may lose one electron and forms metastable ...
