Abstract

Methods and systems of analyzing and quantifying a surface acidity on a low surface area sample are disclosed. The methods include analyzing a quantity of an effluent molecular probe desorption from a temperature programmed desorption (TPD) process and system, by employing a mass spectroscopy (MS) system. The molecular probe is chemically adsorbed on a clean surface of the sample before the TPD process. The sample has a surface area to mass ratio of less than 5 m/g. In some embodiments, the total surface area analyzed in the method can be as low as 3 m.
