一般說明

79-81 °C熔点标准品萘是一种非极性碳氢化合物,用于纯化学品和药物化合物的表征。熔点值是采用根据基准物质校准的Büchi B-545仪器进行 6 到 12 次测量的平均值来确定。

應用

79-81 °C熔点标准品萘是一种分析标准品,用于在热力学分析模式下运行进行熔点仪器的校准。它还适用于研发实验室的化学品质量控制(QC)和质量保证(QA),用于鉴定固体结晶物质并检查其纯度。
此外,这种熔点标准品还可用作热研究中的温度校准标准品。

特點和優勢

  • 熔点校准标准可溯源至基准物质(LGC, London)
  • 等级:分析标准品
  • 标准偏差达± 0.3 °C
  • 随附分析证书和安全数据表
