General description

Matrix modification is a procedure for reducing volatilization and vapour-phase intrusions using a chemical reagent which acts as buffer enabling the use of higher pre-treated and atomization temperatures. The reagent causes either the interfering component to become more volatile or the analyte is converted to less volatile form. Magnesium is a first class modifier, forming oxides in the graphite furnace during heat pre-treatment. Magnesium added as nitrate has high thermal stability.

Application

Magnesium along with palladium may be used as matrix modifier during platform atomization, to determine lead in solution and in soil slurries, using electrothermal atomization atomic absorption spectrometry. It may also be used for determining brain manganese concentrations during graphite furnace atomic absorption spectrometry (GFAAS).
