This paper describes the feasibility of using fluorescence microscopy in conjunction with normal white light microscopy and image analysis in order to carry out fully automated maceral analysis. A short review of current image systems shows a lack of success in distinguishing the liptinite species from the resin media used to form the coal block. Fluorescent lighting is commonly used during manual analysis and in this paper fluorescence is shown to provide a means of performing automated maceral analysis which includes an accurate determination of the liptinite content. The work presented indicates that the system can be used with a wide range of coals from around the world. A realistic assessment of repeatability and reproducibility is also made.
