Mass spectrometry (MS) makes use of the motion of ions in electric and magnetic fields in order to sort them according to their mass-to-charge ratios. Thus, MS is an analytic technique by which chemical substances are identified by the sorting of gaseous ions in electric and magnetic fields. The instruments used in these studies operate on the principle that moving ions may be deflected by electric and magnetic fields. A device that performs this operation and uses electrical means to detect the sorted ions is called a mass spectrometer.© BrainMass Inc. brainmass.com October 24, 2018, 6:30 pm ad1c9bdddf
To answer this posting I will have to tell you what mass spectrometry is in laymans terms first.
Mass spectrometry is a technique where one can analyze the molecular mass of a compound directly. Say you have made a compound X and wanted to be sure that it was what you thought it was, you could analyze the molecular mass of the compound, compare it with the molecular mass that you believe it should be (adding up the elemental masses from the periodic table) and identifying (characterizing) your compound.
There are several different types of MS that are discussed, and ...

products of mass spectrometry and stability
I wonder about a mass spectrometry problem where they define which m/z that would appear for a molecule and why another m/z value does not appear that has a primary radical and a secondary cation. I know that the primary radical is unstable but the secondary cation is more stable than other products. Could one explain this by rate laws or rate constants mathematically? And in general explain which radicals and cations that are formed for normal alkanes?View Full Posting Details
