L-2400 UV/L-2420 UV-Vis Detector

Overview

Superior signal-to-noise even at the fastest response times and a selection of flow cells make the LaChrom Elite Model L-2400 UV and L-2420 UV/Vis Detectors the right choices for any application.

Advanced optics and active electronics combine in the L-2400/L-2420 to provide a new level of performance for UV and UV/Vis detection. Pre-aligned flow cell options accessed from the front of the instrument allow the user to easily switch from micro-bore to conventional or high throughput. Active noise filters with a wide range of response times produce superior signal-to-noise while maintaining peak shape in high flow rate applications. Automatic wavelength calibration and documentation within EZChrom Elite make it easy to comply with government regulations for system suitability.

To improve light intensity and detection sensitivity in the visible range, the L-2420 UV/Vis Detector contains a tungsten lamp in addition to the deuterium lamp.
  • Available with a wide range of flow cell
  • External inputs for lamp off switching and auto zero
  • Variable signal output for best peak presentation
  • Spectrum recording with baseline subtraction for comparisons
