It is an OEM UV detector with SMA 905 connectors enabling the use of an external cell connected by optical cables. It is intended
to be used in preparative and flash chromatography with diode array (DAD) in the range of 190–800 nm.
Multiple wavelengths or the scan are used in liquid chromatography to verify the purity of samples being analyzed or in situations when some peaks absorb at different wavelengths.

The unit is supplied with an AMY17 PCB board. It powers the lamps and controls the unit. It has a lot of new functions including higher speed sampling. The unit is equipped with an RS232 communication port.

Main features and benefits:

  • compact size
  • built-in lamp working hours counter
  • cell connection using optical cables
  • measuring at 4 wavelengths simultaneously and the possibility to see the current scan
  • sophisticated diagnostic software

Note: An external cell and optical cables are not a part of these units and must be ordered separately
