Abstract
A new sample preparation technique has been developed for the analysis of powdered sedimentary organic matter by transmission infrared micro spectroscopy. The resulting spectra are compared to those from (i) sta ndard bulk infrared analysis and (ii) transmission infrared microspect roscopy using a diamond anvil cell. Infrared microspectroscopy leads t o spectra of greater quality than the bulk method, permitting studies of OH bands even when using small quantity of pure organic matter. Thi s new technique is applied to the characterization of a low-rank coal subjected to sequential confined pyrolysis.
