SAPPHIRE EX Detector with optical connectors
is a detector with continuously variable wavelength in the range of 190 – 800 nm and a noise level ± 0.5 x 10-5 AU.
Cell is installed out of unit and it is connected to the unit using fiber optic cable with SMA connectors.
It is possible connect the detector to a cell for ITP or with cell PLCC 20 use it for preparative or flash chromatography.
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.
The detector is equipped with a high standard deuterium and tungsten lamp in a special socket that enables easy changing. Wavelength can be programmatically changed during the performance of an analysis. The detector performs automatic wavelength calibration after the lamp has been switched on.
Cell and fibre optic cable are not include.
