Abstract
A sample sprayer includes a first conduit for conducting a liquid sample, a second conduit surrounding the first conduit to define an annular passage for conducting a gas, a sprayer tip in which a fluid interaction region receives the liquid sample and the gas. The sprayer tip is configured to produce a sample spray by contact between the liquid sample and the gas in the fluid interaction region and emit the sample spray from the orifice. An adjustable positioning device is configured to translate the first conduit along the longitudinal axis in response to adjustment of the positioning device, wherein an axial position of the first conduit is adjustable relative to the orifice.
