Synthetic multiple oxides standards
The WROXI standards set is comprised of 20 synthetic multiple oxides standards supplied as powders to be prepared as fused beads. Standards are supplied as 5g powders in air tight plastic bottles, packed under nitrogen. The full set is housed in an aluminum carrying case containing the standards, user information and concentrations on CD ROM.
Standards are made from pure chemicals, pre-conditioned, weighed, ground and packaged under nitrogen. Detailed instructions on the use and handling of the WROXI standards are included with the application package.
Fused beads are prepared using recipes provided and preprogrammed on the Eagon 2 or using one’s own. Calibrations are created using provided templates in SuperQ which can be adapted and/or extended.
Elements and analytical ranges
The WROXI calibration standards include 21 elements with a wide concentration range covering many materials. The elements and analytical ranges are shown in the figure.
