Waters 2489 UV/Visible Detector 186002487

**This instrument has been tested for basic power function. Unit does NOT include software. See photos for further details.

The Waters® 2489 UV/Visible detector can be used for in vitro diagnostic testing to analyze many compounds, including diagnostic indicators and therapeutically monitored compounds. 

The Waters 2489 UV/Visible Detector is a two-channel ultraviolet/visible (UV/Vis) detector designed for high-performance liquid chromatography (HPLC) applications

The detector can operate either as a stand-alone unit (with a chart recorder or integrator) or as an integral part of a Waters chromatography system. The detector can be configured with Empower™ or MassLynx™ software systems.

Features:
The detector operates from 190 to 700 nm. Also, the instrument uses optics with an
enhanced illumination system for improved performance. These design features increase the optical throughput and sensitivity and reduce bandwidth for an overall increase in signal-to-noise ratio and improved linearity.

The detector has the following capabilities:

  • Stand-alone programmability – Stores up to five user-defined programs (or methods) consisting of up to 50 programmable timed events and two threshold events each.
  • Single or dual wavelength – Monitors absorbance at one or two discrete wavelengths.
  • Wavelength verification reference filter – Ensures wavelength accuracy.
  • Automatic second order filter – Automatically engaged for wavelengths 370 nm and greater and removed for wavelengths 369 nm or less.
  • Spectrum scan and storage – Supports spectrum scan, display, subtraction, storage, and playback, in addition to standard absorbance and UV/Vis functionality.
  • Cuvette qualification – Facilitates qualification of the detector by insertion of a standard in a  cuvette without breaking any fluid line connections. Waters qualification kits are available to support this feature. This feature also allows you to use the detector as a benchtop spectrophotometer.
  • Cuvette sample analysis – Allows the spectrum of any sample placed in the cuvette to be recorded.
  • Method editing and storage – Supports basic method programming, storage, and retrieval from the front panel.
  • Full diagnostic capability – Supports built-in diagnostic tools to optimize functionality and performance.
  • Two contact closure outputs – The detector has two configurable switches, each of which can accommodate a maximum of +30 Vdc, 1.2-A current carry, and 0.5-A current switching. The switches (SW1 and SW2) can trigger fraction collectors and other external devices, as well as activate based on time, absorbance threshold, or ratio criteria.
  • Improved thermal wander management– To mitigate thermal instability caused by ambient temperature changes, the detector has improved insulation (for better air flow across the optics bench) and a variable speed fan that will run at higher or lower speeds as needed.
  • Median Baseline Filter (MBF) - A variation of the data mode, the MBF is intended to decrease the effects of gradient separations on the chromatographic baseline. The MBF enhances the UV detector's baseline stability by decreasing its curvature, making the development of integration methods easier.

The Waters 2489 UV/Visible 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.
