ABSTRACT
A method for the simultaneous determination of oxygen and nitrogen in synthetic diamonds by inert gas high temperature extraction-impulse heating method was proposed. The sample weight, the selection of analysis power and the calibration curves of oxygen and nitrogen were discussed. Oxygen and nitrogen in analytical samples are determined. Values of RSDs (n=7) for oxygen and nitrogen were less than 4. 5% and 4. 0% respectively. The analytical results of oxygen and nitrogen obtained by the proposed method were in good agreement with those by inert gas fusion-impulse heating method.
