What is a differential refractive index detector used in HPLC? A comprehensive and easy-to-understand explanation based on a comparison table with other detectors! Free foundational knowledge materials available!
The differential refractive index detector (RID) detects the difference in refractive index of the eluent from the column containing the mobile phase and analytes. It can be used for the detection of all compounds, but its sensitivity is not very good, estimated to be less than 1/1000 of that of a UV-Vis detector. It can detect compounds that do not have UV-visible absorption or fluorescence, making it useful for detecting sugars and synthetic polymers. This document provides a clear summary of the fundamentals of liquid chromatography (LC), detectors, and principles. It is recommended for those who are learning HPLC for the first time, those who want to review from the basics, and those looking for materials useful for in-house training.
