| Definition | A sample is passed through a nebulizer to create an aerosol and transported via an argon gas stream to an inductively-coupled gas plasma (8-10000 K) where it is dried, melted, evaporated, atomized, then excited. The excited atoms pass through the cooler part of the plasma and de-excite releasing specific-wavelength photons dependent on the element. Emissions are passed to the optical system which measures their intensities, which are directly proportional to the concentrations of the analytes. | |
