  • 摘要: 研究了甲醇中15种有机氯农药长期稳定性和短期稳定性，以寻找合适的长期保存条件和运输条件.长期稳定性考察了-18℃冷冻和室温条件不同贮存时间时样品的稳定性；短期稳定性模拟运输过程中环境温度和运输时间，重点考察高温时样品的稳定性，测定数据采用趋势分析法进行评价.结果表明，甲醇中15种有机氯农药标准样品的长期保存条件为-18℃冷冻，运输条件是在40℃高温下至少可以稳定保存15 d，为后续标准样品稳定性研究提供了参考.
    Abstract: In order to find suitable storage environmental and transport condition for organochlorine pesticides(OCPs)in methanol reference material, long-term stability and short-term stability were discussed. According to directives for the work of reference materials (GB/T 15000), long-term stability was tested in the different time and different temperature such as room temperature and -18℃.And short-term stability was investigated by simulating transport conditions such as temperature and shipping time, especially for high temperature. All the data from stability were evaluated using a linear regression model. The results showed that the long-term stability for OCPs in methanol reference material was -18℃, and the transport was stable for at least 15 days at 40℃. It is reference for the stability of other reference materials.
