Waters 2414 Refractive Index (RID) Detector is designed for high-performance liquid chromatography (HPLC) applications. It provides sensitivity, stability, and reproducibility for the analysis of components with limited or no UV absorption. The solution-centered design combines with Alliance or Breeze HPLC Systems for RI-based HPLC and GPC applications.
Waters 2414 RI Detector provides solutions for preparative and analytical applications including alcohol, sugar, saccharide, fatty acid, and polymer analysis.
Features:
- Low dispersion volume for high-speed GPC and narrowbore column chromatography from 0.1 to 10 mL/min
- Thermally isolated optics bench for temperature stability and performance reproducibility
- Save solvent and maintain stability with convenient recycle valve
- Diagnostics and simplified design and control options for easy maintenance and everyday use
- Circuitry and software in the detector’s thermally isolated optics bench provide a sensitive, stable signal response to changes in refractive index independent of ambient temperature changes
- Auto-zero, auto-purge, and LED-displayed diagnostic programming enable unattended operation and to simplify methods development
