The LED20 Dual UV detector with UV Light Emitting Diodes (LED) as the light source is an OEM built-in UV detector for preparative and flash chromatography.
The dual UV detector version measures at two fixed wavelengths, which are adjusted in production and given by the built-in LEDs.
By default, diodes with wavelengths of 255 and 280 nm are used. Optionally, the customer can select a wavelength in the range of 255–600 nm in steps of 5 nm.
The unit is controlled by an innovative PCB board that powers the LEDs and controls the unit and has many new features including higher sampling speed.
The key features of the LED20 detectors:
- Small dimensions
- Low cell heating due to the low power losses of the LEDs
- Easy flow cell replacement
- Sophisticated diagnostic software
