By use of phase detection in Fourier transform infrared photoacoustic spectroscopy, we are able to obtain new information on materials difficult and often impossible to obtain otherwise. With our technique, a more precise and complete analysis is hereby possible. Applications of our approach to polyethylene, asbestos fibers and a thin layer of polymer illustrate well this capability.
