{"product_id":"magnesium-nitrate-matrix-modifier-solut-5142","title":"Magnesium nitrate matrix modifier solut., 20 g\/l Mg(NO3)2 (99,999 %) in H2O","description":"\u003cp\u003eMagnesium 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.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/icp-aas-and-ion-standards\"\u003eICP, AAS \u0026amp; ion standards\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/analytical-standards-and-reference-materials\"\u003eAnalytical standards \u0026amp; reference materials\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ec (Mg(NO3)2) in H2O: 20 g\/l ±1 %\u003c\/li\u003e\n\u003cli\u003ePack size: 50 ml\u003c\/li\u003e\n\u003cli\u003ePurity: 99,999 %\u003c\/li\u003e\n\u003cli\u003eDensity: ~1 g\/cm³\u003c\/li\u003e\n\u003cli\u003eBoiling point: ~100 °C\u003c\/li\u003e\n\u003cli\u003eConcentration: 20 g\/l Mg(NO3)2\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SPEZ-5142-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwMzA5NHxhcHBsaWNhdGlvbi9wZGZ8YUdVd0wyaGxPUzg1TWpVME9EZzFOemcxTmpNd0wxTlFSVnBmTlRFME1sOUZUaTV3WkdZfGY3MWM2YzEwNGI5YTRjMTQxMDg2NzE1NjMzMWJlMTUyMjhkMGExNjVhYmRlOWYxNWU0MWZlNGQ2ODI0ZTFjMzQ\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/api.carlroth.com\/medias\/SDB-5142-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNTgxODd8YXBwbGljYXRpb24vcGRmfGFESTFMMmd5TkM4NU1qQTJOekUwT1RJMU1EZzJMMU5FUWw4MU1UUXlYMFJGWDBWT0xuQmtaZ3w4ZTE0NmIxYzVlOGI3M2Y0MDZiYThiZWFmMWJkZDJiN2NjZTcwOGUyYWQ1ODExYjllOTY1MTJmYTY4ODhlMGMy\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"SDS PDF\" aria-label=\"SDS PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"50 ml \/ 1 piece","offer_id":56165250040140,"sku":"5142.1","price":203.2,"currency_code":"EUR","in_stock":true},{"title":"50 ml \/ 6+ pieces","offer_id":56165250072908,"sku":"5142.1","price":193.04,"currency_code":"EUR","in_stock":true},{"title":"50 ml \/ 24+ pieces","offer_id":56165250105676,"sku":"5142.1","price":182.88,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/1000Wx1000H-5139_50a7b40d-ebdc-484e-9ac0-e0d94aafd9de.jpg?v=1766439689","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/magnesium-nitrate-matrix-modifier-solut-5142","provider":"Luminix Health","version":"1.0","type":"link"}
