Description
Magnesium nitrate matrix modifier solution provides 10 g/l Mg(NO3)2 at 99,999 % purity in water for graphite furnace atomic absorption spectrometry and related atomic spectroscopy applications. The aqueous preparation shows a density of about 1 g/cm³ and a boiling point near 100 °C, consistent with dilute inorganic salt solutions used as furnace modifiers. Packed as 50 ml from manufacturer Carl ROTH, the solution is intended where magnesium nitrate alone is specified to stabilize analytes, suppress certain interferences, or optimize ashing and atomization temperatures in GF-AAS methods. High stated purity of the magnesium nitrate component supports low blank contribution in trace-element work. Categories of use include atomic spectroscopy (AAS, ICP-OES, ICP-MS sample contexts) and dedicated matrix modifier protocols for graphite furnace AAS. Ready-made concentration reduces preparation time and improves batch-to-batch consistency compared with dissolving solid salts in the laboratory. Clear physical data aid method documentation and safety assessment. This modifier fits routine environmental, industrial, and research laboratories that follow established magnesium nitrate modifier recipes and require a convenient, high-purity aqueous stock.

Questions about Magnesium nitrate matrix modifier solut., 10 g/l Mg(NO3)2 (99,999 %) in H2O
What is this article?
Magnesium nitrate matrix modifier solut., 10 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.
