摘要：

Equations are derived for viscosities of H-2, He, N2 and Ar for use at chromatographic temperatures which are accurate to within 0.3 % for H-2, and 0.1 % for the other gases. The effect of pressure is usually negligible but may increase the viscosity of N2 or Ar by as much as 0.5 % at 25-degrees-C or lower and 5 atm or higher.
