TOYDAD400 EX Scanning Detector

4 channel Scanning 200-400
Is OEM built-in UV diode array (DAD) detector working in range 200 – 400 nm. It measures absorbance at four wavelengths simultaneously or sends scan with speed of 5Hz.  SMA 905 connectors allow to use external cell connected with optical cables. It is suited for preparative and flash chromatography.

More wavelengths or scan are used in liquid chromatography to verify purity of analyzed samples or in situations when some peaks absorb on different wavelengths.
 

Most important features of TOYDAD EX units:

  • small dimensions
  • built-in lamp working hours counter
  • cell connection using optical cables
  • measuring at more wavelengths simultaneously
  • sophisticated diagnostic software
