Volatilisation

For thoughtful child sponsors
Volatilisation is the process whereby a dissolved sample is vaporised. In Atomic Spectroscopy this is usually a two step process. The analyte is turned into small droplets in a nebuliser these are entrained in a gas flow which is in turn volatilised in a high temperature flame in the case of AAS or volatilised in a gas plasma torch in the case of ICP spectroscopy.
