WebThe line at m/z = 29 is typical of an ethyl ion, [CH 3 CH 2] +: The other lines in the mass spectrum are more difficult to explain. For example, lines with m/z values 1 or 2 less than one of the easy lines are often due to loss of one or more hydrogen atoms during the … WebQ: What is mass spectrometry? it is a powerful instrumental method of analysis. It can be used to: - find the abundance and mass of each isotope in an element allowing us to determine its relative atomic mass - find the relative molecular mass of substances made of molecules Q: What are the steps in Mass spectrometry? WebIt is defined as one twelfth of the rest mass of an unbound atom of carbon-12 in its nuclear and electronic ground state, and has a value of 1.660538782 (83)x10 -27 kg.
