【 摘 要 】

Standard water, dimethylamine and unsym hydrazone solutions were prepared and then measured using gas chromatography (GC) in five replicates for each solution. Peak height and area were compared in terms of repeatability. In addition, two kinds of standard curves were fitted separately according to the peak heights and areas measured above. At last, unknown samples were determined. The results showed that among the three kinds of component measured, the average relative errors of peak height and area of each one were no larger than 3.9% and 4.16% separately. Beyond that, both linear dependences of the standard curves plotted through peak heights and areas were higher than 99% and the intercepts were almost the same. It was also found that the absolute deviations of all three components in unknown samples determined through peak height and area were not greater than 0.004%. To conclude, either peak height or area is applicable to the determination of the components in unsymmetrical dimethylhydrazine (UMDH).
