Embodiment Construction

[0093] Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. These examples are provided to provide a further understanding of the invention and not to limit the scope thereof.

[0094] In the following description, a series of steps are described. The skilled artisan will appreciate that, unless required by the context, the order of the steps is not critical to the resulting configuration and its effects. Additionally, it will be apparent to the skilled person that irrespective of the order of the steps, the presence or absence of a time delay between the steps may exist between some or all of the steps described.

[0095] It will be appreciated that the present invention is applicable to elemental and isotopic analysis of solid, liquid or gaseous samples generally utilizing mass spectrometry techniques. Therefore, in general, the samples analyzed in the system will be variable. Additionally, the system and method acc...

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.

Description

[0001] Funding related statement [0002] The work leading to the present invention has received funding from the European Research Council under the European Union's Seventh Framework Program (FP7 / 2007-2013) / ERC grant agreement n° FP7-GA-2013-321209. technical field [0003] The invention relates to a mass spectrometer, in particular to a mass spectrometer with a collision cell with a traction field. The invention furthermore relates to a mass spectrometry method using a collision cell with a pulling field. Background technique [0004] Mass spectrometry is an analytical method for the qualitative and quantitative determination of molecular species present in a sample based on the mass-to-charge ratio and abundance of gaseous ions. [0005] In inductively coupled plasma mass spectrometry (ICP-MS), high sensitivity and precision (concentrations as low as 10 15 1) Detection of atomic species. In ICP-MS, the sample to be analyzed is ionized using inductively coupled plasma...
