Multiply charged ions and method for determining the molecular weight of large molecules

The present invention is a new composition of matter, which is a population of multiply charged ions, 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. Additio...

More Information
Summary:The present invention is a new composition of matter, which is a population of multiply charged ions, 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. Additionally, the invention is a method for calculating the molecular weight of the analyte from the measured mass values of the highly charged ions.
