Certification of a soda–lime–silica glass reference material for XRF-analysis

The preparation, analysis and certification of a new certified glass reference material (CRM) for multi-element determination in soda–lime–silica glass is described. The CRM BAM-S006 is available in the form of discs (thickness: 5 mm, diameter: 40 mm) as well as in form of cullet. Certified properties are the mass fractions of 19 main, minor and trace elements. The certified values are based on the results of 18 laboratories which participated in the certification inter-laboratory comparison. The CRM is intended for establishing or checking the calibration of x-ray spectrometers for the analysis of samples of similar matrix composition as well as for wet chemical analysis.
