Abstract
Devices, systems and methods using counterflow sample introduction are described. In certain examples, the devices, systems and methods may be configured to introduce a fluid flow comprising a sample into a torch comprising a plasma in a direction that opposes the flow of a gas used to sustain the plasma. Optical emission devices, optical absorption devices and mass spectrometers using the counterflow sample introduction are also described.
