  • Fluctuations in lamp intensity are automatically maintained and corrected to reduce noise and drift.
 
  • 20-bit digital electronics greatly enhance quantitative accuracy and precision over a wide dynamic range.
 
  • Time programming of the Ex wavelength and Em wavelength lets you optimise sensitivity and selectivity
 
  • Automatic real time scanning of eluting peaks helps you identify optimum wavelengths.
 
  • Sixty stored spectra can be displayed on the LCD or via an external data system
 
  • Lamp and flow cell are at the front of the detector and come pre aligned for ease of maintenance.
 
  • Biocompatible flow cell available
 
  • Pulsed Xenon lamp. This means no warm up time, the lamp only needs to flash during the run, and a lamp life of 5600 hours on max flash rate, compared to maybe 500 hours for a standard Xenon lamp.
