Definition
Interference due to changes in the volatilization rate of the dry aerosol particles in the case when volatilization of the analyte is incomplete in the presence and/or absence of the concomitant. This interference can either be specific, if the analyte and interferent form a new phase of different thermostability, as when $\ce{Mg}$ and $\ce{Al}$ form $\ce{MgAl2O4}$ in an air–acetylene flame, or non-specific, if the analyte is simply dispersed in a large excess of the interferent, as when $\ce{Ag}$ is dispersed in $\ce{ThO2}$. If the interferent has a high boiling point, this latter is sometimes referred to as a blocking interference. It is often difficult to make sharp distinctions between the specific and non-specific solute-volatilization interferences.
