General description

Matrix modifier in general, is a buffer that is similar to the chemical environment of aqueous standards and samples. It can also make analyte more thermally stable salts, oxides or metal compounds. It also reduces the volatility of analyte.

Application

Palladium matrix modifier may be used in determination of total arsenic by in situ oxidation of diluted urine using graphite furnace atomic absorption spectrophotometer.

Components

Pd(NO3)2.2H2O in 13-20% nitric acid
