Features Header
Filled with innovation - designed for usability
The 2489 UV/Vis Detector is the most sensitive and versatile dual-wavelength absorbance detector available for HPLC. The detector’s advanced features take UV/Vis detection performance to a new level, with:
- 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
Setting the standard for trace impurity analysis
The 2489 UV/Vis Detector offers simplicity for routine UV-based applications and high sensitivity for low-level impurity analysis. The detector’s extended linear range of 2.5 AU enables the identification and quantitation of both major and minor components in the same run - a key benefit for trace impurity or metabolism studies.
More analyte information per run
Dual wavelength capability is standard on the 2489 UV/Vis Detector. This gives you the flexibility to simultaneously monitor absorbance at two user-selectable wavelengths, resulting in more analyte information per run, and increased productivity. The two wavelength channels can be overlaid, ratioed, and/or summarized within the data system for better qualitative data.
Optimal performance across your workflows
Whether you work in research and development, analytical development, or QA/QC, the 2489 UV/Vis Detector is designed to meet your needs with a wide range of flow cell options and integrated features, while providing optimal flexibility, usability, and performance for both routine and complex samples.
