Preferred Label : solute-volatilization interference;
Detailed label : solute-volatilization interference in flame spectroscopy;
IUPAC 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 Mg and Al form
MgAl sub 2 /sub O sub 4 /sub in an air–acetylene flame, or non-specific, if the analyte
is simply dispersed in a large excess of the interferent, as when Ag is dispersed
in ThO sub 2 /sub . 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.;
