Chemical modification should be considered if an analyte is highly volatile, or, if the analyte and matrix volatilize at similar temperatures. Such modification would allow ashing at higher (or atomization at lower) furnace temperatures, resulting in elimination of the matrix with no loss of the analyte (or atomisation of the analyte, but not the matrix). Several compounds are cited in the literature for this application, the most common ones being magnesium and palladium solutions.
