Variable-wavelength UV and UV-vis detectors Designed as modular HPLC components, our variable-wavelength UV (190 – 600 nm) and UV-vis (190 – 900 nm) detectors deliver ultra-high-speed (0.1 seconds), high response, and extremely low operating noise levels to 0.6 x 10-5 AU to meet your toughest analytical requirements. Simple programming allows wavelength scanning and range changes during an analytical run. The inherent stability of the optical design ensures reliable analyses independent of ambient conditions. Automatic wavelength calibration for UV range The detector has a built-in mercury lamp for automated wavelength calibration. The system checks three wavelengths for enhanced reliability in wide-wavelength-range analyses. The lamp shuts down automatically during inactive periods to prolong lamp life, and lamp usage is easily monitored through the front panel keypad and display. Optimized for use with ESA Coulometric electrochemical detection, features include: Double-beam, variable wavelength capability Programmable wavelengths Easy-to-use control pad Wide range of flow cells Automatic lamp startup/shutdown Pre-aligned lamps for easy changeover Remote autozero capability
