Magnesium nitrate matrix modifier solution is a ready-to-use reagent containing 20 g/l Mg(NO3)2 at 99,999 % purity in water, intended for graphite furnace atomic absorption spectro metry (GF-AAS) and related atomic spectroscopy workflows. The aqueous formulation supports controlled matrix modification during sample preparation and atomisation, helping laboratories manage interference effects when analysing complex matrices. Physical characteristics include a density of approximately 1 g/cm³ and a boiling point near 100 °C, consistent with a water-based modifier solution. Supplied in a practical 50 ml pack size (about 0,050 kg), the product is suited to routine method development and day-to-day analytical use in spectroscopy laboratories. This matrix modifier solution from manufacturer Carl ROTH is positioned within atomic spectroscopy applications covering AAS, ICP-OES and ICP-MS support chemistry. High-purity magnesium nitrate in aqueous medium offers a convenient concentration for dilution schemes and standard operating procedures used in graphite furnace AAS matrix modification.
