LED20G Single UV detector suited for preparative and flash chromatography, which thanks to unique ECOM patented technology, radically improves features of detectors that use LED diodes as a source of light spectra.
Usually LED diodes have a peak wavelength with a tolerance of +/- 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 choose the exact wavelength from the LED diode spectra due to our patent technology.
This Single UV detector version measures at one fixed wavelength, given by an installed LED diode.
Standardly are used diodes with wavelength 254 or 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
