The use of spectro(photo)metric reference materials in chemical metrology--present status in Romania.
This paper discusses some aspects of the use of certified reference materials (CRMs) to ensure the uniformity of results, especially through calibration and validation of spectro(photo)metric instrument performance. In this way the link between the intrinsic performance of instruments and the accuracy of measurement results is underlined. Some types of local CRM are also presented.
