1.	Which of the following detectors depend on Snell’s law at the interface between the cell wall and the flowing liquid to deflect the light beam?(a) Electrochemical detectors(b) Fluorescence detectors(c) Refractive index detectors(d) Thermal conductivity detectorsI have been asked this question in final exam.The above asked question is from Detection System of Liquid Chromatography topic in chapter Chromatography of Analytical Instrumentation
Answer» The CORRECT answer is (C) Refractive index detectors To explain: Refractive index detectors depend on Snell’s law at the interface between the cell wall and the flowing liquid to deflect the LIGHT BEAM. Changes in refractive index are monitored by a POSITION sensor.
