Abstract
The invention provides an analytic nebuliser device for delivering a sample in aerosolised form, the device comprising a nebuliser nozzle configured to receive a flow of said sample and generate a plume of aerosolised sample spray and a chamber configured to receive a flow of make-up gas and connecting with a plurality of microchannels having outlets arranged around and adjacent to said nebuliser nozzle wherein the microchannels are configured to produce a make-up gas stream with high linear velocity around said aerosolised sample spray to shape and direct said plume. The invention extends to a mass spectrometry or spectroscopy system including the above analytic nebuliser device, to provide in operation the aerosolised sample spray to an ionisation device of the system.
Claims14
An analytic nebulizer device for delivering a sample in aerosolized form, the device comprising:
- a nebulizer nozzle configured to receive a flow of said sample and generate a plume of aerosolized sample spray;
- and
- a chamber configured to receive a flow of make-up gas and fluidly coupled to a plurality of microchannels, wherein each of the microchannels comprises a microjet outlet, and wherein the microjet outlets are arranged around said nebulizer nozzle and are arranged substantially in a common plane;
- wherein the nebulizer nozzle comprises a central axis and a nebulizer nozzle outlet;
- wherein the nebulizer nozzle outlet is positioned within 5 mm of the common plane;
- and
- wherein the microjet outlets are configured to direct said make-up gas stream substantially parallel to said central axis and to produce a make-up gas stream with high linear velocity around said aerosolized sample spray to shape and direct said plume.
