abstract:Acoustic resonance spectroscopy (ARS) is a method of spectroscopy in the acoustic region, primarily the sonic and ultrasonic regions. ARS is typically much more rapid than HPLC and NIR.
In this paper, the problem of the acousticresonantfrequencyshift of a cylindricalcavity with a coaxialporous sample is discussed on the basisof the resonance acousticspectroscopy.
