GSB 07-1401-2001-甲醇中有机磷农药混合溶液
环境标准样品主要用于环境监测及分析测试中的质量保证和质量控制，亦可用于分析仪器校正、分析方法比对和分析技术仲裁。 本标准样品采用高纯试剂在超净实验室准确配制，分装于2 毫升安瓿内，经均匀性检验合格。其标准值和不确定度是用气相色谱法进行多次重复分析，并经数理统计处理后确定的。 本标准样品应在冰箱中保存。 安瓿中有机磷农药浓度值如下： The Environmental Reference Materials (ERMs) are primarily used in quality assurance and quality control in the process of environmental monitoring and analysis, and it can also be used in analytical instrument correction, analytical method contrast and analytical technology arbitration. This ERM was prepared in super-clean lab with high pure reagents and sub-packed in 2ml ampoules. No significant differences in concentration among sub-samples were found. The certified value and uncertainty were based on the multiple analytical results by GC. It is recommended to store this ERM in refrigerator. The concentration of this ERM in ampoule is as following： 甲醇中有机磷农药 335602Organo phosphorous pesticides in Methanol成 分Component 标准值(µg/ml)Certified value 不确定度(µg/ml)Uncertainty 敌敌畏 64.3 ± 7.9 乐果 94.6 ± 9.6 甲基对硫磷 93.0 ± 6.5 马拉硫磷 96.6 ± 6.5 对硫磷 98.1 ± 8.3
