1290 Infinity II Variable Wavelength Detector

World’s most sensitive and fastest variable wavelength detector

The Agilent 1290 Infinity II Variable Wavelength Detector (VWD) is the world’s most sensitive and fastest detector in its class. Time-programmable wavelength switching provides optimum sensitivity and selectivity for your applications. Even more sample information can be acquired in the dual wavelength mode. Lowest detector noise (<± 1.5 µAU) and baseline drift (< 1 x 10-4 AU/h) facilitates precise quantification of trace levels components. Ultraproductivity can be achieved with fast analysis at up to 240 Hz data rates.

  • Lowest baseline noise and drift results in lowest detection limits for robust quantification of trace level components.

  • Dual-wavelength capabilities offer more analyte information per run.

  • Up to 100% resolution gain in ultrafast LC, at up to 240 Hz data acquisition rate.

  • Wide linear range (>2.5 AU upper limit) - for reliable, simultaneous quantification of primary compounds, by-products and impurities.

  • Electronic temperature control (ETC) – for maximum baseline stability and practical sensitivity under fluctuating ambient temperature and humidity conditions.

  • Automatic wavelength verification provided through the use of built-in holmium oxide filter.

  • Radio frequency identification (RFID) technology for flow cells and lamps provides a new level of data traceability.

  • Early maintenance feedback (EMF) for continuous tracking of instrument usage, in terms of lamp burn time, with user-defined limits and message types.

  • Extensive diagnostics, error detection and displays provided using Agilent Lab Advisor software.

  • Stop-flow wavelength scanning for fast wavelength optimization.
