General description
萘酚黄S是一种以其危险性而闻名的染料。
Application
有关合适仪器技术的更多信息，请参考产品分析证书。如需进一步支持，请联系技术服务。
萘酚黄S可作为分析参考标准品用于以下物种中萘酚黄S的测定：
- 通过固相萃取（SPE）和高效液相色谱（HPLC）-二极管阵列检测（DAD）-离子阱飞行时间串联质谱（IT-TOF-MS3）进行多反应监测（MRM）检测用于食品。
- 通过SPE及后续利用HPLC偶联光电二极管阵列（PDA）检测器的分析用于饮料和糖果。
- 通过吸附柱色谱用于废水样品。
- 用于由著名的19世纪法国画家埃米尔·伯纳德（Emile Bernard）设计的刺绣。
