sapphire 800 uv-vis variable wavelength detector
is a detector with continuously variable wavelength in the range of 190 – 800 nm and a noise level ± 0.5 x 10-5 au.the unit may be used for routine analytical chromatography as well as for preparative chromatography, according to the se-lected cell.the unit is easy to operate, reference and sample signals are available for detector diagnostics as well as information on lamp operating hours.output signal is available in both digital and analogue form on the output connector. it is possible to control the unit using the keypad or an rs232 interface connecting capillaries are led from the detector’s right side panel.the detector is equipped with a high standard deuterium lamp in a special socket that enables easy changing. for visible part of spectrum is used as secondary light source a tungsten lamp. wavelength can be programmatically changed during the performance of an analysis. the detector performs automatic wavelength calibration after the lamp has been switched on. a cell is included as a component of the detector.
