Abstract
The analysis of isotopomers is conveniently performed using a double focusing high mass resolution magnetic mass spectrometer comprising an electric field and a magnetic field by a constant accelerating voltage slightly less than the accelerating voltage corresponding to the masses of the ions comprising the majority of a sample to be analyzed, and scanning part of an ion accelerating voltage so that it varies within a range effectively corresponding to the masses of the ions of isotopomers of the ions comprising the majority of the sample to be analyzed.
