标准品开瓶后的处理方法
打开的容器中的材料应在打开后尽快完全使用。生产商通常没有关于储存在客户实验室的开放容器中的材料稳定性的信息，这就是为什么他们无法保证在较长时间的开放储存后认证值的正确性。打开容器后，某种材料是否会发生变化取决于分析员的判断。有关更多信息，请参阅ERM应用程序说明6
What should I do with opened CRM containers?
Materials from opened containers should be used completely as soon as possible after opening. Producers usually have no information about the stability of material in open containers stored in the customer laboratory, which is why they cannot guarantee the correctness of the certified value after longer periods of opened storage. It is up to the judgement of the analyst whether a certain material will or will not change after opening of the container. For more information see ERM Application Note 6
