    A simple description of how a mass spectrometer works. Note: All mass spectrometers that you will come across if you are doing a course for 16 - 18 year olds work with positive ions. Even if a few atoms in a sample of chlorine, for example, captured an electron instead of losing one, the negative ions formed wouldn't get all the way through the ordinary mass spectrometer

    Mass spectrometry is not a true spectroscopic technique because the absorption of electromagnetic radiation is not involved in any way. Polymers and natural products have low vapor pressure but on pyrolysis, the decomposition products can be analyzed by a mass spectrometer. Mass spectrometry is used widely in organic chemistry to characterize
