Abstract

A new method for the detection and identification of gas molecules and the analysis of their mixtures is proposed. The new process is based on the analysis of the amplitude density function of surface acoustic wave resonator (SAWR) or MOSFET signal(s). The proposed method has the potential to detect and identify very small numbers of molecules, even a single one. When the number of adsorbed molecules is small, the exact number and type can be determined from first principles of combinatorics.
