A method of determining a surface property, eg, porosity, pore size, pore density, pore volume, pore shape, adsorption, desorption, adsorption selectively, of solids in a plurality by contacting the solids with a fluid, measuring the radiation emitted, absorbed, or altered during adsorption of the fluid using a detector, and then determining at least one surface property of the solids from the radiation measurements has been invented. The invention is particularly useful in combinatorial applications in order to evaluate a plurality of solids or mixtures of solids to determine at least one surface property of each of the solids and to sequentially expose each of the solids to different adsorbates.

Procédé permettant de déterminer une propriété de surface d'un solide parmi une pluralité de solides, qui consiste à mettre en contact lesdits solides avec un fluide, à mesurer le rayonnement émis, absorbé ou modifié pendant l'adsorption du fluide à l'aide d'un détecteur, puis à déterminer au moins une propriété de surface des solides à partir des mesures de rayonnement. La présente invention est particulièrement utile dans des applications combinatoires afin d'évaluer une pluralité de solides ou de mélanges de solides pour déterminer au moins une propriété de surface de chacun desdits solides.
