Metrology is the combination of science, technology, and practice of making measurements with controlled and proven accuracy. Metrological measurements are determinations of the magnitude of a property of a material in the appropriate unit for the property in question. Such a determination is held to lead to an absolute value. A metrological measurement involves the quantification of the property, and of the reliability of this quantification. Mass spectrometry has played a significant role in twentieth-century measurement science and has become of key importance in metrological measurements. The purpose of this paper is to demonstrate that high-precision, high accuracy isotope mass spectrometry is a powerful analytical technique that will continue to make major contributions in many branches of science. The role of isotope mass spectrometry in measuring atomic masses and isotope abundances with high accuracy and precision, enabling the atomic weights and fundamental constants to be determined, is therefore described.
