LED20G Dual UV detector suited for preparative and flash chromatography, which thanks unique ECOM patented technology, radically improves features of detectors which use LED diodes as source of light spectra.

Usually LED diodes itself have peak wavelength with tolerance +/- 5 nm and spectral half width 10 – 20 nm, which is for some application not acceptable. But ECOM solution allows to narrow down spectral bandwidth and to choose exact wavelength from LED diodes spectra.

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

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

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 LED diodes low power supply
• easy flow cell replacement
• sophisticated diagnostic software
