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 – 800 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.

 

4 CHANNEL DETECTOR

Spectrophotometric detector LCD 2083.61 with continuously variable wavelengths in the range of 190 – 360 nm is equipped with four cell for preparative chromatography. The cells work simultaneously on the same wavelength. The unit is assembled with digital recorder for data storing. But the output signal is available in analogue and digital form too.
The detector is equipped with a high standard IST deuterium lamp in a special socket making possible an easy changing.
The unit is easy for operating, reference and sample signal is available for detector diagnostics and lamp live reading. It is possible to control it using keyboard or external signals.

 

 

The new DDT-3200 is the first detector of its class with DAD technology. With its versatile possibilities it not only copes with routine analyses but is also capable for special tasks. The device is offered in three stages of expansion:
DAD
1 channel VWD
4 channels VWD

The arrangement with a diode array-monochromator by Carl Zeiss ® enables an clear, easy accessible assembly. The detector is compact and thereby it saves place in the laboratory. Lamps and cells can be replaced simply by the front drawer.
Already in the basic version has the possibility of external triggering, solvent recycling with build-in solenoid-controlled valve driver, the time program for the wavelength switching as well as the inspection of the lamp characteristics.

With the VWD's a option of scanning beyond a defined wavelength range and the RS232/USB interface is offered. A driver for chromatography software "Clarity" is available.

The unit is supplied completely with analytic cell, vis lamp and 2000-hours working D2-lamp.

Dual UV Detector

is a new type of UV detector, which allows measuring absorbance of two wavelengths simultaneously in one cell. This unit is used in liquid chromatography to verify analyzed samples by means of a second wavelength or in situations when some peaks absorb on different wavelengths. It is possible to use the detector in analytical, preparative or flash applications by using different cells. Noise level at 254 nm is ± 1 x 10-4 AU with an empty cell.

A perfect combination with the HD 2-200 pomp
