ECOM TOY18DAD 400 H Scanning UV/PDA Detector

TOY18DAD 400 H Scanning Channel UV Detector is a standalone UV-VIS detector suited for preparative and flash chromatography with diode array (DAD) in range 200 – 400 nm.

Scanning version measures at four wavelengths simultaneously or sends scan with speed 20 Hz which allows to create 3D picture.

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 TOY20DAD 800H detectors:

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