ECOM spol. s r.o. - Model LED20FIX -Single UV Detector

LED20FIX Dual UV Detector is an OEM built-in UV detector suited for preparative and flash chromatography with UV LED diode as a light source.

Single UV detector version measures at one fix wavelength which is given by installed LED diode.

Standardly are used diodes with wavelength 265 and 280 nm.

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 LED20FIX detectors:

• small dimensions
• low cell heating thanks LED diodes low power supply
• easy flow cell replacement
• sophisticated diagnostic software

• Wavelength range 265 or 280 nm, optionally other wavelength
• Number of channels (Signals) One fix wavelength
