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.
