Accurate mass
Experimentally determined mass of an ion of known charge.
Note 1: Can be used to determine elemental composition to within limits defined by both the

accuracy and precision of the measurement.

Note 2: Accurate mass and exact mass are not synonymous. Accurate mass refers to a measured mass, and exact mass refers to a calculated mass.
