Application Note: Measurement of ATR Spectra of Hard and Irregular Shaped Solid Samples Using the Quest ATR Accessory
23 October 2012

Infrared spectroscopy can be used as an analytical measurement technique to identify the molecular constituents of an extremely large range of solid, liquid and gaseous sample types. In this application note the Specac Quest™ ATR accessory is used for the Attenuated Total Reflectance measurement of an irregular shaped, hard solid sample in order to obtain as wide a spectral transmission range of light frequency collection for the sample as possible. It is shown that a broad range of plastic and polymer types in various shapes, forms and hardness can produce high quality, reproducible spectra when the Quest ATR with the diamond ATR puck is used.
