Accurate mass
IUPAC RECOMMENDATIONS 2013
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.
Related Term(s): exact mass
