Fourier transform photoacoustic spectroscopy is an important tool for the study of powdered samples in the infrared spectral region. Its application to catalytic materials is discussed. The photo-acoustic cell is employed as a reaction environment and samples are treated in situ at temperatures up to 400°C at atmospheric pressure. Special features of the measurements that result from the powdered condition of the samples and measurements at elevated temperatures are discussed. The use of photothermal deflection detection for high-temperature high-pressure measurements is examined.
