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.

Abstract: A flow control device for aerosolised sample delivery in an inductively coupled plasma (ICP) analytical system is provided. The device includes a body that at least in part defines a sample flow separating region, the sample flow separating region having a longitudinal flow direction and having an upstream end through which the aerosolised sample enters and a downstream end through which a modified aerosolised sample exits. The body further includes an injection duct having an opening adjacent to the sample flow separating region, the injection duct configured to direct a stream of gas in an injection direction to the sample flow separating region. The injection direction is angled relative to the longitudinal flow direction such that, upon introduction of the stream of gas through the opening, a vortex flow is generated in the sample flow separating region, the vortex flow having a direction counter to the direction of flow of the aerosolised sample to provide control of droplet size in the modified aerosolised sample.
