Overview

A high-resolution mass spectrometer is an analyzer that measures the mass number of organic compounds. The mass number of the sample can be obtained directly by separating the sample ionized by the ion source according to the mass ratio (m/e) of the ions to the charge using a magnetic field. From this value, basic physical property data of the organic compound such as molecular weight and elemental composition can be calculated. It is also possible to clarify the partial structure of the molecule from the mass number of the fragment ions observed at the same time. Since mass spectrometers can measure the mass number of an extremely small amount (p mol order) of a sample, they are also used to identify minute amounts of environmental pollutants and metabolites in living organisms. In this device, EI, CI, FAB method, etc.
