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 a 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
