Abstract	The feasibility of using diffuse reflectance Fourier transform infrared spectroscopy as a rapid non-destructive technique for detecting mould release agent on the surface of epoxy-based composites has been investigated. It has been shown that it is a viable method if the amount of release agent is greater than about 200 μg/cm2. This limit of detection is determined mainly by the effects of front-surface reflection and scattering. These cause some degree of variation in band shapes and relative intensities which makes it difficult to perform spectral subtraction in order to better detect weak features resulting from surface contamination.
