일반 설명
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.
애플리케이션
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).

Drug-induced liver injury (DILI) is a significant concern in drug development due to the poor concordance between preclinical and clinical findings of liver toxicity. We hypothesized that the DILI types (hepatotoxic side effects) seen in the clinic can be translated
