The Refractive Index Detector S 2020 series provides a consistent enhancement of the already successfully established RID models RI2000 and RI2000-F. The RID S 2020 series offers users 3 times higher sensitivity, (compared to RI2000) stability and reproducibility required for optimal RI detection in HPLC / GPC.
Some cells — especially those used in refractive index detectors — are sensitive to pressure. Flow rates or back pressures that exceed the manufacturer’s recommendation will break the cell window. Old or defective lamps as well as incorrect detector rise time, gain, or attenuation will reduce sensitivity and peak height. Faulty or
RI detectors respond to a universal, bulk property of the analyte — its refractive index. Usually referred to as differential refractive index detectors, these detectors detect peaks based on the difference in refractive index between the analyte and the background mobile phase. This is a benefit that makes the detector universal, but also a
Detectors in Liquid Chromatography A. Refractive Index Detector B. Absorption Detector (UV/Vis) C. Fluorescence Detector D. Conductivity Detector E. Electrochemical Detector These detectors differ from those used in GC in that most of them are nondestructive. This makes LC more attractive for purification or preparative-scale work that GC.
Refractive index detectors sense the difference in refractive index between the column eluent and a reference streatu containing mobile phase only. These detectors are the closest to universal detectors in HPLC because any solute can be detected as long as its refractive index is different from that of the mobile phase.
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 detectors because they can detect anything with a refractive index different from the
HPLC Refractive Index Detectors (HPLC RI Detectors) are used with high-pressure liquid chromatographs when detecting substances with limited or no UV absorption. These chemical components included alcohols, sugars, fatty acids, polymers and carbohydrates. Applications where HPLC RI detectors are used include polymer analysis.
Baseline Stabilization When Using Refractive Index Detectors Tips for Daily Analysis Refractive index detectors (RID) are widely used for many substances, such as to analyze components with low UV absorption, but it requires time for the baseline to stabilize, which has no doubt been a source of frustration for many users.

The Series 200 Refractive Index (RI) Detector is a highly stable and sensitive LC and GPC detector for use with compounds that do not have high absorptivity in the UV range, such as polymers, sugars, organic acids, and triglycerides. The Series 200, with its deflection-type design, allows sensitive detec-tion of these compounds with low
