Error in Governing Equation of Reflection Type Refractive Index Detector in Some Literature of Liquid Chromatography
一些液相色谱文献中反射式折光检测器基本方程的错误

It has been shown that for the reflection type refractive index detector, the expressions for the relationship between the transmitted light intensity, I, and the incident light intensity, I_0, in some books about liquid chromatography are invalid. The correct form should be read as follows:where i and r are the angle of incidence and the angle of refraction, respectively.
