Our reference materials have certified values for selected elements or organic compounds. These are determined through our high accuracy measurement techniques and assessments, including:
- method precision
- method trueness
- homogeneity and stability
- measurement uncertainty, per the guide to the expression of uncertainty in measurement (ISO-GUM).
We also produce aqueous ethanol solutions as Australian certified reference materials, in accordance with regulation 48 of the National Measurement Regulations 1999. These legally traceable standards are used for evidential breath alcohol analyser calibrations.
Our certified reference materials:
- come with certificate of analysis and safety data sheets
- are prepared in accordance with ISO 17034 General requirements for the competence of reference material producers.
