研究了挥发性卤代烃溶液标准物质短期稳定性。模拟运输过程中的环境温度和运输时间设计实验方案,重点研究高温因素对甲醇基体卤代烃溶液标准物质稳定性可能带来的影响。研究表明在模拟高温和低温极端的运输条件下,3种卤代烃混合溶液标准物质中涉及的10种卤代烃组分量值稳定,测量值与标准值最大偏差<3%,在不确定度范围内。 The short-term stability of standard reference materials for volatile halogenated hydrocarbons was studied. The simulation experiment was conducted to simulate the ambient temperature and transportation time in the transportation process, and the impact of high temperature on the stability of the standard substance of the methanol-based halogenated hydrocarbon solution was investigated. The results show that under the extreme transport conditions of high temperature and low temperature, the content of 10 kinds of halocarbons involved in the three kinds of halogenated hydrocarbon mixed solution standard materials is stable, the maximum deviation between the measured value and the standard value is less than 3% Range.
