TOY18DAD 800 HK Scanning UV Detector

4 channel Scanning 200-800

is UV (UV-VIS) diode array detector, which allows measuring absorbance of four wavelengths simultaneously in one cell just as measuring of whole spectrum (scan).

Part number

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 RS232, USB or LAN. At the back panel are available four analog outputs and connector for I/O logical input and output signals.

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
the cell is easy to replace from the side of the detector
• powering by 100-240 V AC
• unit can be controlled by RS232, USB, LAN or keyboard
signals are available in analog and digital form
easy service and diagnostic using display and keyboard or by service SW
