LED20G Dual UV detector suited for preparative and flash chromatography.  Thanks to a unique, ECOM patented technology, it radically improves the detectors´ features. LED diodes are used as the source of light.

Usually LED diodes themselves have peak wavelength with tolerance +/- 5 nm and a spectral half width of 10 – 20 nm, which is unacceptable for some applications. However, the ECOM solution allows us to narrow down spectral bandwidth and to choose the exact wavelength from the LEDs spectrum due to our patented technology.

This Dual UV detector version measures at two fixed wavelengths, given by installed LED diodes.

Standardly there are used diodes with wavelengths 254 and 280 nm. 

Customer optional choice of wavelength in the range 254-600 nm with step 1 nm.

The unit is controlled with an ESTER20 PCB board which powers the LED diodes and controls the unit. It has a lot of new functions including higher speed sampling.

The most important features of LED20G detectors:
• narrowed down spectral halfwidth compared with classical LED detectors
• exact wavelength compared with classical LED detectors
• small dimensions
• low cell heating thanks to LED diodes low power supply
• easy flow cell replacement
• sophisticated diagnostic software
