OPAL UV-VIS FIXED WAVELENGTH DETECTOR
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)
The unit may be used for routine analytical chromatography as well as for preparative chromatography, according to the selected 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. It is possible to change the interference filter by customer.
