Abstract
Many types of polymeric organic foams, which comprise items such as thermal insulation, packaging materials, furniture and garment fillings, carpet padding, and so forth, can be sampled directly using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). Some of the advantages of direct DRIFTS sampling include: (1) no sample preparation is required, (2) the method is completely nondestructive, and (3) the method provides more spectral information for characterizing and individualizing particular substances than many alternative techniques do. Several examples illustrating the direct DRIFTS analysis of a variety of foam articles are presented and discussed.
