A fluorescent X-ray analysis was applied to determine the oxygen in both organic and inorganic compounds. A Rigakudenki vacuum path single channel X-ray spectrograph (D-9C, SX type) with a sealed Rh target X-ray tube (3 kW) and lead myristate (2d= 80.5 Å) as an analysing element was used for the determination of oxygen. Exited O Kα was measured by a gas flow proportional counter with aluminum coated 1 μ thick polypropylene film window. Calibration curves were prepared from appropriate standards of both organic and inorganic reagents. Typical conting rate of O Kα spectra for boric acid, lithium carbonate and magnesium oxide were 2326, 145 and 103 counts/sec. and reproducibility expressed as standard deviation of measured intensities were 0.39%, 0.51% and 0.88%, respectively.
