The 50 ml pack weighs 0,100 kg and is characterised by a density of 0,862 g\/cm³, a flash point of 115 °C and a boiling point greater than 218 °C. These data describe the hydrocarbon-oil matrix in which tungsten is dissolved at the stated mass fraction. From manufacturer Carl ROTH, the solution belongs to the analytical chemicals used as metallo-organic standards when atomic absorption spectrometry or inductively coupled plasma methods require an oil-soluble tungsten reference. The 20 cSt hydrocarbon oil vehicle carries the tungsten content, and the density of 0,862 g\/cm³ allows laboratories to relate weighed aliquots to volume when taking portions from the 50 ml unit. Flash point and boiling point values (115 °C and \u0026gt;218 °C) inform handling of the organic matrix. With tungsten fixed at 1000 mg\/kg W, this ROTI®Star standard is used for AAS and ICP determination of W in organic matrices.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 50 ml\u003c\/li\u003e\n\u003cli\u003eDensity: 0,862 g\/cm³\u003c\/li\u003e\n\u003cli\u003eFlash point: 115 °C\u003c\/li\u003e\n\u003cli\u003eBoiling point: \u0026gt;218 °C\u003c\/li\u003e\n\u003cli\u003eConcentration: 1000 mg\/kg W\u003c\/li\u003e\n\u003cli\u003eUNSPSC: 41116107\u003c\/li\u003e\n\u003cli\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.carlroth.com\/medias\/SDB-3LEH-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyNjU1MjZ8YXBwbGljYXRpb24vcGRmfGFEVmhMMmhrTVM4NU1qWTRNelV6TmprMU56YzBMMU5FUWw4elRFVklYMFJGWDBWT0xuQmtaZ3xiNDM1M2I1Y2M1M2ZkZmI2NWM0N2NiMTI1ODFlNTZkOWNiNGU1MDBiYTUyNjYwZjI1ZmVmODAyZmEwOGUzNmUy\" target=\"_blank\" rel=\"noopener noreferrer\" 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-block;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Luminix Health","offers":[{"title":"50 ml","offer_id":58656499827020,"sku":"3LEH.1","price":133.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/3LEH-1.jpg?v=1788331802","url":"https:\/\/www.luminixhealth.com\/fr-fr\/products\/tungsten-standard-solution-roti-star-1000-mg-kg-w-in-20-cst-hydrocarbo-3leh","provider":"Luminix Health","version":"1.0","type":"link"}
