UV-Vis detector LED20G EX

UVLEDindustrial

The LED20G EX detectors with UV-VIS light emitting diodes (LEDs) as the light source are standalone UV-VIS detectors for preparative and flash liquid chromatography, where it is needed to use an external cell connected by optic cables. The LED20G EX detectors use unique ECOM patented technology that significantly improves the performance of these LED detectors. Why the ECOM LED20G series detectors have the best parameters on the market among LED detector. To explain the difference, the LEDs themselves typically have a peak wavelength tolerance of ± 5 nm and a spectral half-width of 10–20 nm. This is unacceptable for some applications, as e.g. FPLC, and it also causes nonlinearity. However, ECOM‘s solution allows to narrow the spectral bandwidth and to select the exact wavelength from the LED-diode spectrum. Key features and benefits of LED20G EX detectors: • Sharp, high and symmetrical spectral peaks thanks to ECOM-patented technology • Excellent linearity • Excellent price-performance ratio • Compact device dimensions • Low cell heating due to LED´s low power supply (0.7 W) that allows use for peptide analysis or FPLC • Higher sampling speed • Sophisticated diagnostic software • Diodes with wavelengths of 254 and 280 nm, other wavelengths available on request
