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.
