DETERMINATION OF BINARY GAS-PHASE DIFFUSION-COEFFICIENTS USING CHROMATOGRAPHY

Binary diffusion coefficients of 15 organic vapors in nitrogen carrier gas were measured by using the peak arrest technique on a Hewlett-Packard 5840A gas chromatograph with a flame ionization detector. The experiments were conducted at atmospheric pressure, above the normal boiling point of the organic vapors. The experimentally obtained values were compared with those predicted by using various correlations and reported in literature. In general, the observed values were in excellent agreement with the values predicted by Fuller's correlation.
