Superior signal-to-noise even at the fastest response times and a selection of flow cells
Advanced optics and active electronics combine in the LaChrom Elite® L-2400/L-2420 Detectors 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 Empower™ 2 software 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
