Pike Technologies Inc.'s transmission/specular reflectance autosamplers are used with commercial FTIR spectrometers. They are available on an 8-in. circular sampling plate design that can accommodate up to 60, 13-mm pellets, or on a 12-in. plate with more than 100, 13-mm pellets. The autosamplers are suitable for analysis of KBr pellets, polymer films and slides. Reflective samples can be analyzed in the specular reflectance mode.
