	abstract = {Metrology in  environmental science has gained significant  importance over the last couple of years reflecting the need for quality control and harmonization of measurement results. Accreditation , new European directives and finally the highly competitive market require standards with respect to metrology and uncertainties attached to the measurement results. International measurement evaluation studies (.;g. IMEP- international measurement evaluation programme, organized by the EC-Joint Research Centre IRMM) underline the need of reliability and comparability of measurement results. It is well recognised in environmental science that the uncertainty of the measurement step is not necessarily the dominant factor. Nevertheless, many papers published in the field of environmental analysis continue to contain little or no information about the total uncertainty attached to the published values of the quality of results produced, which can only partially be explained by the lack of CRM.
		Isotope ratio analysis capabilities and the high sensitivity make ICP-MS an important tool in metrology. Isotope dilution mass spectrometry (ID-MS) leaves ICP-MS as method of choice, especially if several sample preparation steps are involved. Nonetheless, ID-MS does not necessarily require the use of expensive instrumentation like e.g. MC-ICP-MS, if the repeatability of the isotopic measurement is not the main dominant factor
