Mass spectrograph

...Chromatography is an indispensable tool in environmental science because it is used to confirm and identify trace amounts of chemical substances (mainly organic compounds) remaining in environmental media such as the atmosphere and hydrosphere, or in living organisms, due to its effectiveness in analyzing multi-component samples or trace analysis.
[Mass spectrograph]
The devices used in mass spectrometry are collectively called mass analyzers, which can be classified into deflection type (magnetic field type) and non-deflection type. The former separate masses by the difference in the deflection trajectories of ions within a uniform magnetic or electric field, and include single-focusing mass spectrometers (Figure 1) and double-focusing mass spectrometers, while the latter include quadrupole mass spectrometers (Figure 2) and time-of-flight mass spectrometers. …
