Abstract
A mass spectrometer comprises an ion source (11), an ion injection arrangement (12), field generator defined by shaped electrodes (14, 16) and a detector (18) to detect ions. The electrodes (14, 16) are shaped so as to provide therebetween a field of substantially hyper-logarithmic form whereby ions can be trapped within a potential well of the field for analysis.
Claims22
A mass spectrometer comprising an ion source to produce ions to be analyzed, electric field generation means to produce an electric field within which said ions can be trapped and detection means to detect ions according to their mass/charge ratio wherein said electric field defines a potential well along an axis thereof and said ions are caused to be trapped within said potential well and to perform substantially harmonic oscillations within said well along said axis, said ions having rotational motion in a plane substantially orthogonal to said axis.
