Mass-to-charge ratio has been used occasionally for the horizontal axis in a plot of a mass spectrum, although the quantity measured is not the ion’s mass divided by its electric charge (SI units kg C–1). However, m/z is recommended as an abbreviation to represent the dimensionless quantity that is used almost universally as the independent variable in a mass spectrum. [IUPAC]

titer
type: ObjectProperty
sub property of: concentration
