Leírás és Paraméterek

Flash 14 DAD 600 is an UV diode array detector (DAD,PDA), that allows measuring absorbance on four wavelengths simultaneously in one cell just as visualization of whole spectra. 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 200 up to 600 nm in increments of 1nm
  • Visualization of whole spectra
  • Supportin Clarity SW and ECOMAC
  • Lamp work hours are counted using a built-in counter
  • Lamp is easy exchangeble from detector front panel
  • Powering 90–264 V
  • Unit is controlled through RS232 interface
