Mass Spectrometry in Measuring Masses of Atoms, Molecules, and Their Complexes: Brief Review of Progress

rs Summaries of mass spectrometry (MS) data relating, firstly, to ions of the heaviest nondegraded molecules and larger particles and, secondly, to highly accurate mass ( m / z value) measurements are presented. Atomic masses were measured with relative accuracy up to 0.01–0.1 ppb, masses of petrole...

Summary:rs Summaries of mass spectrometry (MS) data relating, firstly, to ions of the heaviest nondegraded molecules and larger particles and, secondly, to highly accurate mass ( m / z value) measurements are presented. Atomic masses were measured with relative accuracy up to 0.01–0.1 ppb, masses of petroleum constituents and other low-molecular-weight compounds were determined with accuracy up to 1–10 ppb. Ions of proteins with molecular weights >150 kDa, their large complexes, and other bioparticles, and also nanoparticles with masses up to 30 GDa have been recorded. In such research, electrospray ionization, including native MS versions, as well as various versions of high/ultrahigh-resolution MS, and charge detection MS are prevalent. Trends of development and MS records are briefly discussed.
