BRAINCAKEMass Spectrometry of Organic Compounds
A mass spectrometer is used to find the relative molecular mass of an organic compound and to give information about its structure.
Inside the instrument, molecules of the sample are ionised. An electron is usually removed, forming a positive ion called the molecular ion, M+:
M(g) → M+(g) + e−
