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.[1]

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.[2] It may also be used for determining brain manganese concentrations during graphite furnace atomic absorption spectrometry (GFAAS).[3]
