Isotopically characterised N₂ O reference materials for use as community standards.

ABSTRACT:

Rationale

Information on the isotopic composition of nitrous oxide (N₂ O) at natural abundance supports the identification of its source and sink processes. In recent years, a number of mass spectrometric and laser spectroscopic techniques have been developed and are increasingly used by the research community. Advances in this active research area, however, critically depend on the availability of suitable N₂ O isotope Reference Materials (RMs).

Methods

Within the project Metrology for Stable Isotope Reference Standards (SIRS), seven pure N₂ O isotope RMs have been developed and their ¹⁵ N/¹⁴ N, ¹⁸ O/¹⁶ O, ¹⁷ O/¹⁶ O ratios and ¹⁵ N site preference (SP) have been ana
