Instrumentation and Working Principles Principles of Mass Spectroscopy
Mass spectroscopy is the most accurate analytical tool to weigh the molar masses of a given molecule. The principle consist of ionizing the sample in the gas phase to formed positively charged ion or radical ions and then measure the mass to charge ratio of all ions. It is largely used in industry and academia and finds application in chemistry, Biotechnology, pharmaceutical, environmental, Clinical, Geological fields. Different methods use different techniques for ionisation which intern determines what types of samples can be analyzed by mass spectrometry. Of all available methods Electron Ionisation or Impact mass spectroscopy is the most widely used.
