摘　　要：目的研制1种活性炭管中的三氯乙烯标准物质,用于工作场所空气中三氯乙烯检测的量值溯源及质量控制。方法采用直接加入法在活性炭管中加入已知浓度的三氯乙烯标准溶液,熔封后得到标准样品。采用气相色谱法对样品进行均匀性和稳定性研究,并通过双人定值对标准物质确定量值。结果制备的活性炭管中三氯乙烯质量控制标准物质具有良好的均匀性,在常温下可稳定保存1年以上。通过对制备的质量控制标准物质进行定值分析,低浓度标准值为(283.7±5.8)μg,高浓度标准值为(677.5±10.2)μg。结论研制1种活性炭管中三氯乙烯质量控制标准物质,符合国家标准物质研制技术要求,可用于职业卫生实验室检测质量控制、分析方法研究以及量值溯源。[Objective]To develop a certified reference material of trichloroethylene in carbon tubes, which can be used in the traceability and quality control of trichloroethylene in the air of workplace. [Method] The standard solution of trichloroethylene with known concentration was added in activated carbon tube by direct addition method, to obtain the standard sample after sealing. The homogeneity and stability of the samples were studied by gas chromatography method, and the standard value was determined by two researchers. [Results] The certified reference material of trichloroethylene in carbon tubes had good homogeneity and kept stable for more than one year at normal temperature. The analysis on the quality control standard material showed that the low content standard value was（283.7 ±5.8） μg and high content standard value was（677.5 ±10.2） μg.[Conclusion] A certified reference material of trichloroethylene in carbon tubes is developed, and it meets the technical requirements of national standard material development, which can be used in the quality control, analysis method study and traceability in occupational health laboratory.
