OPAL EX Detector with optical connectors
is a detector with an interference filter. By means of this filter can be this unit adjusted at one fixed wavelength in range of 200 – 600 nm. Noise level at 254 nm is ± 0.5 x 10-5 AU with an empty cell. (Filter is not include price)
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 lamp or tungsten lamp in a special socket that enables easy changing.
Cell, interference filter and fibre optic cable are not include.
