Description
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 spectrometry (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.

Questions about Magnesium nitrate matrix modifier solut., 20 g/l Mg(NO3)2 (99,999 %) in H2O
What is this article?
Magnesium nitrate matrix modifier solut., 20 g/l Mg(NO3)2 (99,999 %) in H2O is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
