一般說明

柠檬黄(Cl 19140)也称为酸性黄23,是一种多聚阴离子水溶性染料。作为一种磺酸染料,可通过对氨基苯磺酸与3-羧基-1-(4-磺酸苯基)-5-吡唑啉酮的反应合成。

應用

在使用离子对液相色谱-光电二极管阵列-电喷雾质谱检测器法对食品样品中柠檬黄进行测定时,可采用本品柠檬黄作为参考标准品。
柠檬黄也可用于荧光桃红-柠檬黄法染色细胞包涵体,如病毒聚集体和嗜酸性粒细胞颗粒。可替代Mallory三色染液中的橙黄G,也可配制甲基紫-柠檬黄混合液,染色粪涂片和黏膜刮片中的隐孢子虫。

We demonstrate a method for measuring optical loss simultaneously at multiple wavelengths with cavity ring-down spectroscopy (CRD). Phase-shift CRD spectroscopy is used to obtain the absorption of a sample from the phase lag of intensity modulated light that is entering
Helen Waechter et al.
Analytical chemistry, 81(21), 9048-9054 (2009-10-10)
Analytical UV absorption detection for microfluidic devices, capillary electrophoresis, and even high-performance liquid chromatography is hampered by the small detection volumes, short absorption paths, and the need to sample at a high rate with a stable background and low noise.
