Part number

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.

When using the fiber-optic cables we supply, we recommend to use 1m fiber-optic cables.
For 3 m and 5 m fiber-optic cables, we recommend consultation according to the application.

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
