Development of a new compact high resolution sector inductively coupled plasma mass spectrometer

Abstract

There is an infinite set of geometries which will form a double focusing mass spectrometer. The design process which is used to determine a suitable geometry for the application has often been strongly influenced by the mass range required of the instrument. The types of geometry an organic spectrometer has are largely a result of this, and a brief overview of the design process for this type of application is described in this paper. A spectrometer for elemental use has less of a constraint from the mass range and can follow a different design path. A set of design criteria for an elemental spectrometer is discussed, and an overview is given of how these different objectives are achieved in the latest generation of sector mass spectrometers for elemental ICP-MS.
