Wavelength-dispersive x-ray fluorescence (WDXRF) was used for the determination of carbon in coal and ash samples. A rhodium side-window tube was used for C Ka excitation and a synthetic multilayer crystal (2d = 12.2 nm) for excited radiation analysis. The samples, undiluted or diluted with boric ac

The C31 a~ (22S/ 22S+22R) hopane and C29 aaa (20S/20S+20R) sterane ratios show least variation through the
