Description
Palladium-magnesium nitrate matrix modifier is a ready-to-use solution containing 2 g/l Pd(NO3)2 and 10 g/l Mg(NO3)2 in nitric acid, formulated for graphite furnace atomic absorption spectrometry. The aqueous acidic matrix has a density of approximately 1 g/cm³ and a boiling point near 100 °C, matching typical dilute nitric acid reagent behaviour on the bench. Supplied in a 50 ml pack from manufacturer Carl ROTH, this modifier is applied in atomic spectroscopy workflows (AAS, and related ICP sample preparation contexts) where palladium and magnesium nitrate together stabilize selected analytes during thermal pretreatment and atomization. Matrix modifiers help reduce interferences, improve peak shape, and support more robust calibration when complex sample matrices are analysed. The defined metal concentrations simplify method setup and reduce in-house dilution steps. UN number 3264 applies for transport classification of the corrosive liquid. Laboratories performing routine or research graphite furnace AAS can integrate this solution into existing modifier protocols without reformulating stock mixtures, supporting consistent day-to-day performance in environmental, materials, and quality-control analyses.

Questions about Palladium- Magnesium nitrate matrix mod, 2 g/l Pd(NO3)2, 10 g/l Mg(NO3)2 in HNO3
What is this article?
Palladium- Magnesium nitrate matrix mod, 2 g/l Pd(NO3)2, 10 g/l Mg(NO3)2 in HNO3 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.

What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
