Mass number and isotopes

Definition of mass number (A) and atomic (proton) number (Z). Explain the existence of isotopes Mass spectrometer The principles of a simple time of flight (TOF) mass spectrometer, limited to electrospray ionisation, acceleration to give all ions constant kinetic energy, ion deflection, ion detection, data analysis. The mass spectrometer gives accurate information about relative isotopic mass and also about the relative abundance of isotopes.
