| 摘 要： | 采用固体吸附-毛细管气相色谱法测定环境空气中偏二甲肼的含量，色谱峰高与偏二甲肼浓度在0～13．8mg／L范围内线性关系良好，当采样体积为60L时，检出限和测定下限分别为0．37μg／m^3和1．2μg／m^3。低、中、高3种浓度的偏二甲肼标准溶液测定结果（n=6）的相对标准偏差分别为3．5％，2．6％，1．9％，样品加标回收率为84．5％～101．0％。

| Abstract: | The unsymmetrical dimethylhydrazine （ UDMH ） in ambient air was determined by solid adsorption-capillary gas chromatography（GC）. The result showed that good linearity between the peak height and the content of unsymmetrical dimethylhydrazine was obtained in the range of 0-13.8 mg/L, the detection limit and determination limit were 0.37 μ g/m3 and 1.2 μ g / m3 respectively when sampling 60 L air. RSD（n=6） of the determination results of low, medium and high concentration of standard solution were 3.5%, 2.6% and 1.9%, respectively. The recovery was in the range of 84.5% -101.0%. |
