Paper Abstract

Coupling thin layer chromatography (TLC) with diffuse reflectance infrared spectrometry facilitates the analysis of coal extracts. Like coal itself, the extracts are composed of a complex mixture of many different components. After the easy, inexpensive TLC separation of the extracts into broad classes, the components are transferred simultaneously to a series of cups from which their diffuse reflectance spectra may be measured. The cups are packed with a chalcogenide matrix, which is transparent through much of the mid infrared. Because chromatographic resolution is preserved in the transfer, infrared spectra of all the separated component classes may be obtained. Studying various extracts of three different coals allows for investigation of the molecular differences between them thus providing valuable information concerning the structure of coal.
