Abstract
An ion source is disclosed comprising a nebulizer arranged and adapted to emit a liquid spray, a first target arranged downstream of the nebulizer, wherein the liquid spray is arranged to impact upon the first target, and a sample target arranged downstream of the first target, wherein a sample to be analyzed is provided at the sample target.
Claims18
An ion source comprising:
- a nebuliser arranged and adapted to emit a liquid spray;
- a first target arranged downstream of said nebuliser, wherein said liquid spray is arranged to impact upon said first target;
- wherein said ion source further comprises:
- a sample target arranged downstream of said first target, wherein a sample to be analysed is provided at said sample target.
1 more element
A method of ionising a sample comprising:
- emitting a liquid spray from a nebuliser;
- causing said liquid spray to impact upon a first target arranged downstream of said nebuliser;
- and
- providing a sample to be analysed at a sample target arranged downstream of said first target.
1 more element
An ion source comprising:
- one or more targets
- a sample target downstream of said one or more targets;
- a first device arranged and adapted to cause a stream predominantly of droplets to impact upon said one or more targets to ionise said droplets and to ionise one or more analytes provided at said sample target;
- a second device arranged and adapted to vary the temperature of said sample target with time or to allow the temperature of said sample target to vary with time;
- and
- a third device arranged and adapted to determine a time at which said one or more analytes are released from said sample target.
