摘要：

This paper reports P-rho-T data for pure nitrogen measured with a high-pressure, single-sinker magnetic suspension densimeter (MSD) at (265, 293, 298.15, 350, and 400) K. The MSD yields data with less than 0.03 % estimated error over the pressure range of (10 to 200) MPa. A comparison of the experimental data to the equation of state (EoS) developed by Span et al. indicates they are consistent at pressures below 30 MPa. The EoS has a relative uncertainty with respect to density of 0.02 % over this range. At higher pressures. the density predictions of this model agree with the experimental data reported in this paper within a 0.05 % deviation band.
