Inductively coupled plasma mass spectrometer with mass correction

Abstract:

Systems and methods for controlling mass filtering of polyatomic ions in an ion beam passing through an inductively coupled plasma mass spectrometer (ICP-MS). Polyatomic ion mass data representative of the exact mass of a polyatomic ion having a target isotope is determined. A control signal is generated based on the determined polyatomic ion mass data and output to an ICP-MS to filter based on mass the polyatomic ions in the ion beam traveling through the ICP-MS to an ion detector.
