Very often, authors examine only one carbon black sample of a given type, admitting that the determined characteristics can be extended to all other samples having the same producer specifications. But, due to the variability of the raw materials, that are natural products, and the variability of the process, the surface properties will vary more or less from one batch to another. Nevertheless, the batch to batch stability of filler is of a main importance in the industrial applications. The present work will demonstrate that inverse gas chromatographic methods provide a simple way to test the surface properties of a solid.
