英文摘要	Traditionally-suggested combustion time of 1 h at 550degreesC with the sealed-tube combustion method for determining the C-13/C-12 ratio of cellulose nitrate or other nitrogen-containing components could produce large negative deviation up to 1%.. Three types of cellulose are used to ascertain possible causes. The presence of nitrous oxide (N2O) formed during combustion is most likely responsible for this deviation. Prolongation of the combustion time (at least 5 h at 550degreesC) and intimate contact between copper oxide and organic matter can greatly improve the analysis precision and effectively reduce this deviation to an acceptable level. Regardless of scattered carbon isotope data, hydrogen isotope data are all reproducible within 2% when this method is coupled with the high temperature uranium reduction method. Thus, care should be taken for determining carbon and nitrogen isotope compositions of nitrogen-containing substances using the low temperature sealed-tube combustion method.
