The type, strength, and number of acid sites on solid catalysts can be key factors in determining their performance.  Various methods exist for the measurement of these properties and include infrared methods using the adsorption/desorption of weak base molecules, NMR, gas adsorption/desorption, and reaction of probe molecules in microreactor systems.  There is no absolute acidity measurement for solid materials. Therefore each of these methods provide only a measure of acidity properties under the conditions of the test, such as the sample pretreatment condition, probe molecule used and adsorption/desorption conditions.   This presentation will provide an overview of the types of acidity and some techniques that can be utilized to provide information on the type, number, and strength distributions.<br/>
