TOY18DAD 400 I Scanning UV Detector

4 channel Scanning 200-400

The 200 - 400 nm Scanning PDA detector measures at four wavelengths simultaneously or sends a scan with a speed of up to 20 Hz which allows to create a 3D picture.

More wavelengths or a scan are used in liquid chromatography to verify the purity of analyzed samples or in situations when some peaks absorb on different wavelengths. Thanks to new board features it allows the sending of spectra with high resolution and speed up to 20 Hz depending on the baud rate. 

The unit is supplied with an AMY17 PCB board of dimensions 100 x 160 mm (3.94 x 6.30 in). It powers the lamps and controls the unit. 

The most important features of TOYDAD I detectors:
• small dimensions
built-in lamp working hours counter
easy replacement of the flow cell
measuring at more wavelengths simultaneously
sophisticated diagnostic software
