| Abstract: | A method of determination of trace nitrogen in the light oil sample is introduced. The AN- TEK9000 element analysis equipment was used to determine the trace nitrogen of naphtha distillate by putting the sample with micro injector manually. The result showed that this method could determine the lower nitro- gen content, the relative standard deviation was less than 5%, the relative error was less than 10%. The method can be applied to determination of trace nitrogen in light oil sample because of its simple operation, accuracy, repeatability and high selectivity. |
