A differential refractometer (DRI), or refractive index detector (RI or RID) is a detector that measures the refractive index of an analyte relative to the solvent. They are often used as detectors for high-performance liquid chromatography and size exclusion chromatography. They are considered to be universal .

They are often used as detectors for high-performance liquid chromatography and size exclusion chromatography.The Waters 2414 Refractive Index (RI) Detector defines the standard of excellence for differential refractive index detectors that provides for a streamlined user experience. The detector offers the flexibility to use as a stand-alone or as part of any Waters HPLC system.
Differential refractometers are available for HPLC, but refractive index measurements are temperature sensitive, and good temperature control is essential if high sensitivity is required. The main advantage of the refractive index detector is wide applicability.
Differential refractive index (RI) detector. An RI detector detects components based on the refraction of light in solution. As shown in Figure2, the flow cell of an RI detector is divided into the sample-side and reference-side cells. Prior to analysis, eluate is introduced into either cell, until the flow of the eluate becomes equilibrated.The Optilab is a unique dRI detector for standard HPLC/GPC with 256 times the detection power and 50 times the dynamic range of every other RI detector for chromatography in existence today, making it a valuable addition to any MALS setup.The 2410 differential refractometer can measure extremely small changes in refractive index to detect the presence of sample. The small difference in RI between a reference solution and a sample solution is referred to as ∆ n . ∆ n is expressed in refractive index units (RIU).
A refractive index (RI) detector, also called a differential refractometer, measures refractive index when light is passed through an analyte-containing cell as compared to a reference cell containing just solvent.On-line Differential Refractometers for HPLC and UHPLC. Optilab ™. An on-line differential refractometer with extended range for universal concentration and dn/dc measurements. The Optilab provides both exquisite sensitivity and 50 times the dynamic range of every other RI detector available.The 1260 Infinity III RID is an HPLC refractive index detector (RID) detector that provides excellent performance for entry-level UHPLC and HPLC differential refractometer (DRI) experiments. Rapid equilibration times and stable baselines make it easy to analyze carbohydrates, triglycerides, organic acids, and pharmaceutical excipients.
