Refractive Index Detector. 1. The RI detector is one of the few universal detector available in LC. 2. Principle: The RI detectors measure a bulk property of the mobile phase leaving the column: its ability to refract to bend light (i.e., its refractive index). This property changes as the composition of the mobile phase changes 1 Dec 2012 The refractive index (RI) detector is unique among common liquid chromatography (LC) detectors because it is truly universal in its detection capabilities. LC detectors based on the absorbance of ultraviolet (UV) light are the most popular detectors because they are simple, reliable, sensitive, and respond to 13 Feb 2003 This manual covers the Agilent 1260 Infinity Refractive Index Detector.

Inheriting the stability and extensibility that are the strengths of the Prominence series, the new RID-20A model of differential refractive index detector is designed with a new reference-cell auto-purge feature and validation support function. Principles. The refractive index (RI) detector is the only universal detector in HPLC. The detection principle involves measuring of the change in refractive index of the column effluent passing through the flow-cell. The greater the RI difference between sample and mobile phase, the larger the imbalance will become. Thus 24 Jul 2010 Bulk property detectors are the most universal detectors for HPLC as they measure properties common to all analytes by measuring differences in the mobile phase with and without the sample. One of the most com- mon bulk property detectors is the refractive index detector. Given the uni- versal nature of and troubleshooting the Waters 2414 Reflective Index Detector. It also includes appendices for safety warnings and specifications. Intended use of the Waters 2414 Refractive Index Detector. The 2414 Refractive Index (RI) Detector is designed for high-performance liquid chromatography (HPLC) applications. It provides 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 This limit of detection is probably around. 106 g mL1. The refractive index detector was one of the first online detectors to be developed and was described by Tiselius and Claesson in 1942. It was also one of the first online liquid$
