If you do not receive an email within 10 minutes, your email address may not be registered, Since MS is all about measuring the nuclear mass, it takes full advantage of this natural phenomenon to get a plethora of information extremely valuable when doing MS analysis and interpretation of results. Example: In the EI mass spectrum of water (shown above) a large peak is seen at m/z value 18. From learning to quickly recognise from the spectrum if the analyte is aliphatic or aromatic in nature; to learning to interpret the number of carbon atoms, heteroatoms and degree of unsaturation; and understand isotopes, isomers, logical losses, cleavages and rearrangements to produce a mass spectral fingerprint of the compound.
