It is used as a benchmark in chemical analysis. Most analyses are rather comparative than absolute measurements. The analytical instruments show a relative signal which must be correlated to a known concentration of the analyte. This procedure is comparable to the gauging of a kitchen scale. In order to enable the scale to show you accurate readings it needs reference weights.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Reference material &#8211; A material, that relating to one or more predetermined properties is sufficiently homogenous, stable an determined to be fit for purpose within the confines of a measurment procedure.<\/p><cite>ISO Guide 30:2015, 2.1.1<\/cite><\/blockquote>\n\n\n\n<p>All analytical results, i.e. the content of heavy metals in soil must be verifiable and traceable. as demanded by national and international norms (DIN-, EN- and ISO). This requires so called matrix-matched reference materials. Soils for soils, ore for ore and ceramics for ceramics. There are three main apsects to a reference material: Homogeneity, purity and stability. Often it is difficult enough to fulfill one of these aspects, even more so when developing a method to produce materials suitable for micro-analysis.<\/p>\n\n\n\n<p>Latest news posts:<\/p>\n\n\n<ul class=\"wp-block-latest-posts__list wp-block-latest-posts\"><li><a class=\"wp-block-latest-posts__post-title\" href=\"https:\/\/www.my-standards.com\/blog\/2025\/09\/25\/advancing-carbonate-calibration-new-insights-and-a-next-generation-nano-pellet\/\"><strong> Advancing Carbonate Calibration: New Insights and a Next-Generation Nano-Pellet<\/strong><\/a><\/li>\n<li><a class=\"wp-block-latest-posts__post-title\" href=\"https:\/\/www.my-standards.com\/blog\/2025\/08\/14\/live-webinar-recap\/\">Live Webinar Recap<\/a><\/li>\n<li><a class=\"wp-block-latest-posts__post-title\" href=\"https:\/\/www.my-standards.com\/blog\/2025\/07\/29\/our-journey-to-scc-05-np\/\">Our journey to SCC-05-NP<\/a><\/li>\n<li><a class=\"wp-block-latest-posts__post-title\" href=\"https:\/\/www.my-standards.com\/blog\/2025\/03\/20\/how-to-build-your-custom-pressed-pellet-set-for-xrf-32-mm\/\">How to Build Your Custom Pressed Pellet Set for XRF (32 mm)<\/a><\/li>\n<li><a class=\"wp-block-latest-posts__post-title\" href=\"https:\/\/www.my-standards.com\/blog\/2024\/05\/28\/an-exciting-new-project-the-development-of-a-sulphide-nano-pellet-as-a-reference-material\/\">An exciting new project: the development of a Sulphide-Nano-Pellet as a reference material<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>An insight into the considerations behind the use of a reference material.
