DEVELOPMENT OF REFERENCE MATERIAL OF HOLMIUM OXIDE FOR SPECTROMETERS WAVELENGTH CALIBRATION: FEASIBILITY STUDIES
Journal Title: Periódico Tchê Química - Year 2017, Vol 14, Issue 27
Abstract
The use of certified reference material (CRM) in chemical analyzes is an important requirement in quality assurance systems, since it allows the metrological traceability of results, thus achieving valid and comparable results. This work describes the development and production of holmium oxide reference material that, after certification, will be used in the calibration of the wavelength range of UV-Vis spectrometers and also the necessary feasibility studies to establish the measurement parameters to be used in the next steps of the material production and certification.
