Abstract

See full text

An apparatus and method are provided for analyzing samples of molecules. The apparatus comprises a mass analysis system including a differential mobility spectrometer, which includes at least three filter electrodes defining two ion flow paths where the filter electrodes generate electric fields for passing through selected portions of the sample ions based on the mobility characteristics of the sample ions. The differential mobility spectrometer also includes a voltage source that provides DC and RF voltages to at least one of the filter electrodes to generate the electric field, a first and a second ion inlet that receive sample ions, and an ion outlet that outputs the selected portion of the sample ions. A mass spectrometer receives some or all of the selected portion of the sample ions.
