甲醇中咪鲜胺溶液标准物质

用途
本标准物质可作为工作标准，用于日常分析和检测；也可用于仪器校准、分析方法确认与评价、测量过程质量控制及技术仲裁与认证评价等。

样品制备

本标准物质采用纯度经准确定值的咪鲜胺( CAS : 67747-09-5 )为溶质，以甲醇为溶剂，在室温20±3℃洁净实验室中采用重量-容量法配制而成。

特征量值及扩展不确定度

标准值的扩展不确定度主要由原料纯度、称量、定容以及均匀性、长期稳定性等不确定度合成。

包装、储存及使用

包装:本标准物质采用包装,规格1.2mL携带或运输时应有防碎裂保护。储存及使用:冷藏密闭及避光条件下保存。使用前应于室温(20±3℃)平衡,并充分摇动以保证均匀。安瓿瓶一经打开,应立即使用，不可再次熔封后作为标准物质使用,使用中严格防止沾污。

Application
This standard substance can be used as a working standard for daily analysis and testing; it can also be used for instrument calibration, analytical method confirmation and evaluation, measurement process quality control, and technical arbitration and certification evaluation.

Sample Preparation

This standard substance is prepared using prochloraz (CAS: 67747-09-5) whose purity has been accurately determined as the solute, methanol as the solvent, and the weight-volume method in a clean laboratory at room temperature of 20±3°C.

Characteristic value and expanded uncertainty

The expanded uncertainty of the standard value is mainly synthesized by the uncertainty of raw material purity, weighing, constant volume, uniformity, and long-term stability.

Packaging, storage and use

Packaging: This standard material is packaged, and the specification 1.2mL should be protected from shattering when carried or transported. Storage and use: Keep it under refrigerated airtight and protected from light. Before use, it should be balanced at room temperature (20±3℃) and shake well to ensure uniformity. Once the ampoule is opened, it should be used immediately. It cannot be used as a standard substance after being re-sealed. Strictly prevent contamination during use.
