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 15):
A method of transmitting elemental ions through a reaction cell in a mass spectrometer, the method comprising:\n i. providing at least one multipole ion guide within the reaction cell; ii. applying an axial electric field gradient in the multipole ion guide for improving transmission of ions through the reaction cell; iii. transmitting ions in an axial direction through the multipole ion guide wherein the axial electric field exerts a force upon the ions in the direction of transmission,\n wherein the axial electric field gradient can be adjusted so that during a mass analysis, a first element is analysed with a first \n 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 \n iv. transmitting ions from the ion guide into a sector field mass analyzer for mass analysis followed by detecting ions using a multicollector.
