Abstract

We determined the factors that affect the measurement error of the refractive index n in a flowing liquid (a change in its absorbance and temperature). When a flow-through differential refractometer is used to measure the refractive index of a flowing liquid, the error in measuring is additionally affected by the scattering of radiation in the cell converter and the wedge shape of the cell glasses. A new differential refractometer is developed designed for studying the effect of the absorbance of a flowing liquid on the measurement error of the refractive index. New results are obtained confirming this effect, and a new procedure for compensating it is proposed.

流动液体的吸光度对使用示差折光仪测量的折射率误差的影响

摘要

我们确定了影响流动液体中折射率n的测量误差(其吸光度和温度的变化)的因素。当使用流通式差示折光仪测量流动液体的折射率时,测量误差还受到单元转换器中辐射的散射和单元玻璃楔形的影响。开发了一种新的示差折光仪,用于研究流动液体的吸光度对折射率测量误差的影响。获得了新的结​​果来确认这种效果,并提出了一种新的补偿方法。
