SPD-20A/AV UV/VIS detectors have expanded linear range (up to 2,5AU) and highest sensitivity also in dual channel mode. The extremely low baseline noise and the excellent wavelength precision allow to achieve constant high precision chromatographic analysis. Even if the SPD-20A/AV is operated in stand alone mode, the complete functionality such as wavelength programming or wavelength scans is applicable using the build in keyboard. SPD-20A with built-in D2 lamp covers a wavelength range from 190-700 nm. The SPD-20AV UV/VIS detector with built-in D2- and Tungsten-Halogen lamp covers a wavelength range from 190-900 nm. An improved optical system and higher-order digital filter increases the signal to noise ratio, improves the wavelength accuracy, wavelength reproducibility and expands the wavelength range of the successful previous models. The thermostatic flow cell improves baseline stability especially when using mobile phases with absorbance that fluctuates easily due to temperature changes. The above listed improvements lead to the result that the SPD-20A/AV has the lowest baseline noise and baseline drift among the currently available HPLC UV/VIS detectors. Maintenance works are simplified because of easy access to the detector cell and pre aligned lamps. Build ion validation functions, as automatic wavelength accuracy test, a built-in Mercury lamp for wavelength calibration, maintenance - and error- logs supporting work according to GLP/GMP. Simply by changing the detector flow cells the UV/VIS detectors can be customised for all kind of applications from micro LC up to preparative LC.
