Waters 2420 ELSD- Evaporative Light Scattering Detector Waters 2420 ELSD- Evaporative Light Scattering Detector Waters 2420 ELSD- Evaporative Light Scattering Detector – Universal detector with high sensitivity to the compounds, without chromophore. The device is designed to analyze a broad range of compounds, such as hydrocarbons, polysaccharides, lipids, vegetable oils, fatty acid oligomers. The 2420 is an excellent alternative to refractometric detectors to work in the gradient, works with a wide range of mobile phases and additives, including ion-pair reagents. 2420 detectors less sensitive to the fluctuations of the mobile phase and temperature than refractometric detectors. 2420 detector can be operated as part of the Alliance or the system with mass spectrometer under the direct control software Empower or MassLynx (with option FractionLynx), or can operate as a separate module.   Technical specifications: Optical System Optics Optical bench with a heated (constant temperature of 50 ° C). Light Source Polychrome tungsten halogen lamp, mounted on the front panel, set at the factory, can be installed user. The timer Lamp History of the lamps on the clock and the inclusion of being on the serial number. Calibration lamps Sizing / normalization of photomultiplier tubes to compensate for degradation over time. Detector Photoelectric multiplier. Sizing FEU Individually for each FEU, is via a built-in diagnostics. The range of stresses 0-1250 VDC. Normalization of lamps Special diagnosis based on demand and when you turn adjusts the decline in output lamps. Thank you for looking at our items.
