Scanning electron microscopy (SEM) and wavelength-dispersive spectrometry (WDS) were used to determine organic oxygen in four geographically diverse coals and in amber. Subsequent to the previously reported feasibility study, analytical modifications and refinements in sample handling and preparation were made. In addition, the precision of the SEM-WDS analyses was examined. SEM-WDS results were comparable to values obtained by neutron activation and by the indirect ASTM procedure for one coal, while significant discrepancies were observed for the other coals and the amber.
