The LED20 EX detectors with UV Light Emitting Diodes (LED) as a light source are OEM built-in UV detectors for preparative and flash chromatography for use with an external cell.
The single UV LED detector version: measures at one fixed wavelength, which is defined by the installed LED.
The dual UV LED detector version measures at two fixed wavelengths, which are adjusted in production and determined by the built-in LED.
Wavelengths: By default, diodes with wavelengths of 255 and 280 nm are used.
Optionally, customers can select a wavelength in the range of 255–600 nm in steps of 5 nm.
Control: 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 flow cell and optical cables: Must be ordered separately. You can select from our wide range of our External preparative cells and Tri-clamp cells categories on our website: https://www.ecomsro.com/cells/external/filtry/application:preparative-and-flash
Interface: I/O interface
Key features and benefits of LED20 EX detectors:
• Compact size
• Low cell heating due to the low power losses of the LEDs
• Easy flow cell replacement
• Higher sampling speed
• Sophisticated diagnostic software
