摘　　要：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 the volatile halohydro- carbon mixtures in methanol was invesitigaed by simulating transport eonditionssuch as storage temperature and time. The higher temperature stability of three kinds of mixed solutions which includes 10 halohydrocarbon components was empha- sized. The short-term stability test results show that the value of halohydrocarbon components in methanol matrix solutions is stabile, the relative deviation between the measurement value and certified value is less than 3% , which is in the range of uncertainty of the reference material.
