Whether performing routine UV-based applications or pushing the limits of detection with low-level impurity analyses, the Waters 2489 UV/Visible (UV/Vis) Detector is the best detection choice for performance, reliability, and usability. The 2489 UV/Vis Detector is the most sensitive and versatile dual-wavelength absorbance detector available for HPLC. The design combines a high energy Deuterium source, a precise optical design, and low noise, high speed electronics. These advanced capabilities take UV/Vis detection performance to a new level.
Features:
- Enhanced sensitivity via patented TaperSlit™ flow cell, which channels light through the cell for better energy throughput while minimizing RI effects
- Low noise performance (<5 µAU)
- Lamp optimization for the best s/n performance over the lifetime of a Deuterium lamp
- Flexible sampling rates, from 1 to 80 Hz, for normal and fast LC separations
- Independent optimization of sampling rates and filter time constants gives you the ability to tune your detector to your separation goals
- Enhanced thermal wander management reduces baseline wander due to fluctuations caused by ambient conditions
- Flow cell options to match your separation scale and type
- Accessible detector components for easy operation and maintenance
