Flash 10 DAD 800 Detektor

Cikkszám: ECOM Flash 10 DAD 800 Detektor

Leírás és Paraméterek

Flash 10 DAD 800 is an UV-VIS diode array detector (PDA,DAD), which allows measuring absorbance of four wavelengths simultaneously in one cell 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 peaks 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 by RS232. At the back panel are available four analog outputs.

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

  • absorbance measuring on four wavelengths simultaneously
  • wavelength setting from 190 up to 840 nm in increments of 1nm
  • on-line scan of whole spectrum
  • 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 90–264 V
  • unit is controlled by RS232 and keyboard 
  • signals are available in analog and digital form
  • easy service and diagnostic using display and keyboard
  • adaptation for external cell connection available
