Abstract
Devices, systems and methods including a spray chamber are described. In certain examples, the spray chamber may be configured with an outer chamber configured to provide tangential gas flows. In other instances, an inner tube can be positioned within the outer chamber and may comprise a plurality of microchannels. In some examples, the outer chamber may comprise dual gas inlet ports. In some instances, the spray chamber may be configured to provide tangential gas flow and laminar gas flows to prevent droplet formation on surfaces of the spray chamber. Optical emission devices, optical absorption devices and mass spectrometers using the spray chamber are also described.
