2489 UV/Visible (UV/Vis) Detector for Purification and Modular LC Systems Whether performing routine UV-based applications or pushing the limits of detection with low-level impurity analyses, 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
