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.

The unit is supplied with AMY17 PCB board. It powers the lamps and control the unit. It has lot of new function including sampling higher speed.

Most important features of TOY18DAD U units:

  • small dimensions
  • easy replacement of flow cell
  • built-in lamp working hours counter
  • measuring at more wavelengths simultaneously
  • sophisticated diagnostic software
