Gas Chromatograph Data at Infinite Dilution

In gas chromatograph measurements the experimental information obtained from the experiments is usually in terms of retention volume or net retention volume. 

The retention volume extrapolated to zero column pressure, VN°, is related to the partitioning of the solvent in the gas and liquid phases by (Patterson et al., 1971) 

Mj = molecular weight of component i, kilograms per kilomoles. At infinite dilution 

Nonideal gas behavior is accounted for by introducing the fugacity coefficient of component 1 in the gas mixture. 

The standard state fugacity is calculated from Equation (4C-17). Combining the expressions for the ratio of fugacity to concentration and standard state fugacity
