| In addition to its use as an analyzer of liquids, polymers and darkly colored rubber materials, the attenuated total reflectance (ATR) accessory can be used to study several layers of laminated polymers. By varying the angle of incidence, depth profiling studies can be carried out. Numerous industries including magnetic recording tape, floppy disks, photographic film emulsions and printing/publishing could routinely make use of this technique for the analysis of multilayer films.
