  • Additive manufacturing of microanalytical reference materials
    Patent number: 12286355
    Abstract: A method includes acquiring particles doped with at least one analyte and forming a monolithic reference material. The method includes forming includes using the analyte-doped particles as feedstock particles in an additive manufacturing process. A product includes a monolithic reference material formed of Stöber particles doped with a trace element. A method includes acquiring particles doped with platinum group elements (PGEs). The method includes forming a monolithic reference material using the PGE-doped particles as feedstock particles in an additive manufacturing process.
