The LED20M FIX detectors with UV Light Emitting Diodes (LED) as light source are stand-alone UV detectors for flash chromatography. Why choose LED20M FIX detectors for your application: The LED detectors allow easy and convenient detection in the UV-VIS range. They are manufactured in single or dual channel models with fixed wavelength setup. The detectors are widely used in chromatography techniques using gravity glass columns for purification and isolation of organic small molecules and other compounds of interest. Long lasting and reliable light source is provided by LED. The optical flow cell is easily accessible and replaceable, this feature allows flexible choice of detection sensitivity if required. Low cell heating due to low power dissipation of LEDs makes this detector ideal for applications where analytes may be susceptible to degradation due to elevated temperatures. Absorbance information is displayed in detail on the integrated OLED display in numerical and graphical formats. The units have convenient USB-C connectivity and power. When the detector is connected to a PC, the recorded data can be stored and processed using the ECOMAC software. ECOMAC basic software license is available with the price of the product without any additional fees. All these features and capabilities allow LED20M FIX to be an affordable, cost-effective, reliable and robust choice of an UV-VIS detector. The single UV LED detector version measures at one fixed wavelength, which are adjusted in production and determined by the built-in LED. The dual UV LED detector version measures at two fixed wavelengths. By default, diodes with wavelengths of 255 and 280 nm are used. Optionally, customers can select a wavelength in the range of 255-600 nm in steps of 5 nm. Control: The detector can work without any additional SW support, but it is also possible to interconnect it via USB-C cable to a PC with ECOMAC SW, to get a data set for later use or to get reports for unit diagnostics. An innovative PCB board powers the LEDs and controls the unit, and has many new features, including higher sampling speed. Key features and benefits of LED20M FIX detectors: • Affordable, cost-effective, reliable and powerful choice of an UV-VIS detector • Practical OLED display with numerical and graphical view mode • Long lifetime of the LED light source • Low cell heating due to low power losses of the LEDs • USB C powering and communication port • Autozero function • Easy flow cell replacement • Small dimensions • ECOMAC SW - sophisticated software for data acquisition and for diagnostics (ECOMAC Basic software included in the price of the product) Continued on next page
