LED20FIX Dual UV Detector is an OEM built-in UV detector suited for preparative and flash chromatography, with a UV LED diode as a light source.
The dual UV detector version measures at two fixed wavelengths adjusted in production and is given by the installed LED diode.
Standardly there are used diodes with wavelength 255 and 280 nm.
Customer optional choice of wavelength in the ranges 255-600 nm with step 5 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 LED20FIX 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
