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 …
