4 channel scanning 190-800nm

SKU: TOY20DAD 800 VEX Category:


UV (UV-VIS) diode array detectors, which allow measuring absorbance of four wavelengths simultaneously in external cell connected by optical cables, just as measuring of whole spectrum (scan).More wavelengths are used in liquid chromatography to verify purity of analyzed samples or in situations when some substances absorb on different wavelengths. It is possible to use the detector in flash and preparative applications.

It is possible to control the detector manually by keyboard and display but also using RS232USB or LAN. At the back panel are available four analog outputs and connector for I/O logical input and output signals.

When using the fiber-optic cables we supply, we recommend to use 1 m fiber-optic cables.
For 3 m and 5 m fiber-optic cables, we recommend consultation according to the application.

The unit’s DAD (diode array detector) design offers many advantages:

  •        absorbance measuring on four wavelengths simultaneously.
  •        wavelength setting in increments of 1nm.
  •        on line scan of whole spectrum with speed up to 20 Hz which allows to create 3D picture.
  •        lamp work hours are counted using the built-in counter for both deuterium and halogen lamps.
  •        SMA connectors at front panel allows easy connection of external cell.
  •        powering by 100-240 V AC.
  •        unit can be controlled by RS232USBLAN or keyboard.
  •        signals are available in analog and digital form.
  •        easy service and diagnostic using display and keyboard or by service SW.
