Abstract

This paper describes the chemical identification of solid samples in the size range of 8-250um in diameter. The samples are usually inhomogeneous and range from polymer inclusions to fibres. While scanning electron and optical microscopy are usually the first line of analysis for such samples, they cannot yield chemical identification when the sample is organic. A combination of infrared microscopy and spectral library searching provides a powerful technique in the industrial laboratory and examples are shown of polymer inclusions, laminates, fibres and filter deposits. The spectra were obtained using a Spectra-Tech IR Plan Microscope coupled to the external port of a Nicolet 5DXC FTIR spectrometer whose main compartment houses an MTEC Photoacoustic (PAS) Cell. The complementary facets of PAS and infrared microscopy are also highlighted.
