Abstract:
The invention provides a mass spectrometer that comprises a collision cell having an axial electric field that enhances transmission of light ions, especially elemental ions, through the collision cell, relative to heavier ions. The invention also provides methods of mass spectrometry that employ an axial electric field that is provided in a collision cell.

Claim (Index 22):
A method of increasing sensitivity of an elemental mass analysis in a mass spectrometer, the method comprising:\n i. providing an ion beam comprising at least one elemental ion into a multipole reaction cell; ii. applying an axial electric field gradient in the reaction cell, wherein the axial electric field gradient can be adjusted so that during a mass analysis, a first element is analysed with a first setting of the axial electric field gradient in the reaction cell and a second element is analysed using a second setting of the axial electric field gradient in the reaction cell; and iii. analyzing an ion abundance or isotope ratio of the at least one elemental ion transmitted through the multipole reaction cell using a multicollector,
