Abstract

The Japanese word “masu” originates from the English word “mass.” It is occasionally used as an alias for units of mass and m/z. However, mass of molecules and ions should be expressed with the unified atomic mass unit (unit symbol: u) or dalton (unit symbol: Da). Furthermore, the m/z value indicated in the abscissa of mass spectra is dimensionless; therefore, it should not have any units.
