| Abstract: | The calibration gases of alcohol in nitrogen with about 10-6 were prepared in the form of diffusion tubes by dynamic volumetric method, the uncertainties of the calibration gases were in the range of 2%-3%. And the calibration gases were verified by the static volumetric method. The relative error was 3.5%-4.0% by the results. |
