Abstract
The invention provides (a) a time-of-flight mass spectrometer with an acceleration region, a single-stage or multi-stage reflector, and an ion detector, further comprising an additional reflector whose potential has, at least in a subregion, a two-dimensional logarithmic potential component and a two-dimensional octopole potential component, and (b) methods for operating the time-of-flight mass spectrometer.
Claims13
A time-of-flight mass spectrometer comprising:
- an acceleration region;
- a single-stage or multi-stage reflector;
- an ion detector;
- and
- an additional reflector whose potential has, at least in a subregion, a two-dimensional logarithmic potential component and a two-dimensional octopole potential component.

A method for operating a time-of-flight mass spectrometer, comprising:
- accelerating ions in an acceleration region;
- passing the ions through a first reflector after a first field-free flight region;
- passing the ions through a second reflector after a second field-free flight region;
- and
- detecting the ions in an ion detector after a third field-free flight region, where one of the two reflectors is a single-stage or two-stage reflector and the other is a reflector whose potential has, at least in a subregion, a two-dimensional logarithmic potential component and a two-dimensional octopole potential component.
