摘要：

A modified Leitz hot stage fitted to a Spectra-Tech microscope and interfaced with a Nicolet 20-SXC Fourier transform infrared (FT-i.r.) analyser was used to collect infrared (i.r.) spectra from a series of heat treated coal or kerogen samples. Hot stage modifications included installation of an i.r. transparent ZnSe cover disc and routing of a microthermocouple to the interior of a 50 mul platinum sample pan. Spectra were collected in the reflected light mode prior to and then during or after heat treatment. This provided a means to monitor organic functional group changes or depletion resulting from heat treatment. Obstacles encountered and their solutions are discussed.
