Description
Summary:This paper studies the traceability of the certified value of the reference material with the equivalent water content of nitrogen tetroxide(NTO) and green nitrogen tetroxide(MON), which lays the foundation for the certified value of the reference material. The purity of bibenzyl was measured by differential scanning calorimetry(DSC), the water content of deuterium acetonitrile(DAN) was measured by Karl Fischer method, the proton content and water content of deuterium acetonitrile(DAN) were measured by nuclear magnetic resonance spectroscopy(NMR), and the equivalent water content of deuterium acetonitrile(DAN) - nitrous oxide system was measured. All of these three methods can be directly traced to SI units, which are internationally recognized potential reference measurement methods. Therefore, the fixed value of equivalent water content reference material has metrological traceability.
