Leírás és Paraméterek

Flash 14 DAD 800 is an UV diode array detector (DAD,PDA), that allows measuring absorbance on four wavelengths simultaneously in one cell just as measuring of whole spectrum (scan). This unit is used in liquid chromatography for verification of analyzed samples by means of four wavelengths or in situations, when some peaks absorb on different wavelengths. It is possible to use the detector in flash and preparative applications.

The unit is designed as standalone with 90-264 V power supply and RS232 controlling.

The DAD detector design offers many advantages, such as:

  • Continuous 5 Hz scan or absorbance measuring on four wavelengths simultaneously
  • Wavelength setting from 190 up to 840 nm in increments of 1nm
  • Lamp work hours are counted using a built-in counter
  • Lamp is easy exchangeble from detector front panel
  • Clarity PDA module support for 3D measuring
  • Powering 90–264 V
  • Unit is controlled through RS232 interface
