Optical Detection Systems Bio Photometric Detection System Absorbance @ 260nm [AU] Choose the wavelength data you want to see. In many nutrient, water purity and process applications, full spectrum analysis is not required. With LEDspec you can eliminate the extraneous data and focus on those wavelengths you need to see. You can conduct flow analysis and single-scan applications with high precision over a large dynamic range. 2 spectrophotometer 1.5 R 2 = 0.9981 2 µL sample volume 1 0.5 0 0 100 200 300 400 500 600 LEDspec R 2 = 0.9927 SPECTROSCOPY ● Affordable spectroscopy ● Dynamic range and baseline noise outperform CCD and photodiode array based spectrometers ● LED light source eliminates costly replacement lamps ● Integrated reference channel eliminates signal drift ● Full computer control ● Integrated math functions allow for baseline correction at a second wavelength, signal ratio and more ● Simplified display with just the data you want to view ● Your choice of three wavelengths included Two models are available: 2-channel and 4-channel. LEDspec-2 (2-channel) comes with your choice of three LED modules (wavelengths). LEDspec-4 (4-channel) also includes your choice of three LED modules, however, up to four additional wavelengths can be added, if desired.
