Description

The Waters 2414 Refractive Index Detector, P/N 186241400, is well-suited to analyze compounds that are without strong UV chromophores, fluorophores, or electrochemical or ionic activity. RI detectors are used to analyze carbohydrates and lipids and in polymer analyses by gel-permeation or size-exclusion chromatography. RI detectors work by measuring changes in the bulk properties of the solvent and the solutes under investigation, exploiting the improbability that solvents and solutes would share the identical refractive index.
