Abstract
A production of mass spectra which contain a multiplicity of peaks. The component ions of these peaks, which are multiply charged, are formed by dispersing a solution containing an analyte into a bath gas as highly charged droplets. The analyte is generally a compound of high molecular weight and is of biochemical interest. The methods calculate the molecular weight of the analyte from the measured mass values of the highly charged ions.
