The Waters 2410 Differential Refractometer (RID) is a differential refractive index detector designed for high performance liquid chromatography applications. It can operate as a stand-alone unit with an integrator or chart recorder, or with a Waters system controller or Waters data system.
Features:
- Patented countercurrent heat exchanger and temperature-controlled cell for stable operation under varying conditions
- Auto zero and auto purge for automated operation
- Built-in pressure relief to protect flow cell
- Auto diagnostics
- Two external column heater controls
- Battery backup to retain parameter settings when the detector is powered off or during power interruptions
- Long-life LED light source
