- Abstract:
- For ensuring the traceability and uniformity of measurement results, the main objectives of national metrology in chemistry are to calibrate and verify measuring instruments, to evaluate the uncertainty of measurement results, to intercompare the analytical results etc. The concept of traceability has developed recently in chemical measurements, thus, an attempt to implement the principles of metrological traceability especially by appropriateness calibration using the composition certified reference materials (CRMs), are underlined. The paper presents some aspects and practices in the field of spectrometric measurements regarding the metrological quality of the traceability by calibrating the instruments using suitable and reliable CRMs. The uncertainty of the results, as a measure of the reliability that can be placed on them, has been adequately described in different documents, and, as a consequence, some examples of evaluating the measurement uncertainty are described. The relationship between uncertainty and traceability, as two fundamental concepts of metrology which are intimately linked, is underlined.
