| Abstract: | The traditional moisture trap method and semi-conductive refrigerate technique were combined to remove the moisture.The new technique could reduce the amount of reagent,the sample volume,as well as the consumption of carrier gases.The interference of water vapor was eliminated and N2O in solution was determined by gas chomatography,the variance coefficient of the instrument is better than 0.6% after 15 h operation. |
