A New Application of McReynolds Constants to the Characterization of the Chromatographic Properties of Stationary Phases

An algorithm was proposed for comparing the McReynolds constants of new gas-chromatographic stationary phases with data for not only well-known individual substances but also their binary combinations. It was found that, in most cases, sets of these parameters for the chromatographic properties of new stationary phases are inconsistent with the data for a restricted set of previously characterized phases; however, they are consistent with the properties of phase combinations. This can be interpreted in terms of the absence of specific properties. Exceptions were found only among stationary phases bearing some specific molecular fragments (such as nitro groups) and individual crown ethers.
