Abstract
An ion source is provided comprising one or more nebulisers and one or more targets, wherein the one or more nebulisers are arranged and adapted to emit, in use, a stream predominantly of droplets which are caused to impact upon the one or more targets and to ionise the droplets to form a plurality of ions. The ion source further comprises one or more electrodes arranged adjacent to and/or attached to the one or more targets wherein the one or more electrodes comprise one or more apertures, notches or cut-outs wherein at least some of the plurality of ions pass, in use, through the one or more apertures, notches or cut-outs.
Claims22
An ion source comprising:
- one or more nebulisers and one or more targets, wherein said one or more nebulisers are arranged and adapted to emit, in use, a stream predominantly of droplets which are caused to impact upon said one or more targets and to ionise said droplets to form a plurality of ions;
- and
- wherein said ion source further comprises:
- one or more electrodes arranged adjacent to and/or attached to said one or more targets wherein said one or more electrodes comprise one or more apertures, notches or cut-outs wherein at least some of said plurality of ions pass, in use, through said one or more apertures, notches or cut-outs.
A method of ionising a sample comprising:
- providing one or more nebulisers and one or more targets;
- causing said one or more nebulisers to emit a stream predominantly of droplets which are caused to impact upon said one or more targets and to ionise said droplets to form a plurality of ions;
- positioning one or more electrodes adjacent to and/or attached to said one or more targets wherein said one or more electrodes comprise one or more apertures, notches or cut-outs;
- and
- causing at least some of said plurality of ions to pass through said one or more apertures, notches or cut-outs.
