Abstract
Recently, rapid developments in mass spectrometry have enabled people who do not have adequate knowledge of chemistry to operate mass spectrometers. In addition, some sales engineers dealing with mass spectrometers have little knowledge of chemistry because they did not major in chemistry, when in university. However, basic knowledge of chemistry and mass spectrometry is necessary to obtain optimum results and to highlight the favorable points of their instruments. In this paper, we present some basic knowledge of chemistry and mass spectrometry as a short tutorial course for the abovementioned persons.
