Description
Agilent 1260 Infinity II G7162A Refractive Index Detector (RID) Overview
The Agilent 1260 Infinity II G7162A Refractive Index Detector (RID) measures a refractive index range of 1.00 to 1.75 RIU with drift under 200 x 10⁻⁹ RIU/hr, making it well suited to detecting non-UV absorbing compounds such as carbohydrates, lipids, and polymers. Using electronic temperature control (ETC), it maintains a stable optical unit temperature up to 55°C, delivering consistent, reproducible results with minimal baseline drift.
The RID is a strong fit for gel permeation chromatography (GPC) and size exclusion chromatography (SEC) applications, where refractive index detection is essential for compounds lacking UV chromophores. An 8 µL sample cell with automatic purge and solvent recycle valves keeps operation efficient and minimizes solvent waste, while automatic light intensity adjustment compensates for lamp degradation and flow cell staining over time, reducing maintenance needs.
A maximum data rate of 74 Hz supports high-speed data acquisition even for narrow peaks, and the detector’s thermal design allows for fast start-up, typically ready to use within two hours of installation.
This Agilent 1260 Infinity II G7162A Refractive Index Detector (RID) is offered fully refurbished and tested, in working condition, by Alliant Scientific.
