Optical Detection Systems Bio Photometric Detection System Absorbance @ 260nm [AU] SPEC TROS CO PY 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. ● 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 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 ● 700 800 DNA [µg/mL] ● ● ● ● DNA Calibration Curve using WPI's V-Vette combined with a LEDspecUV and pharmaceutical compliant spectrophotometer. LEDspec ● Applications include: ● Measures visible wavelengths ● Sample cells: LWCC, Fiber Optic Cuvette Holders, V-Vette ● Wavelength range (nm): 400, 450, 540, 560, 600, 650, 700, custom Environmental/Oceanography Ammonia at 650nm Iron at 560nm Nitrite/Nitrate at 540nm Phosphate at 700nm Pharmaceutical Process Control Semiconductors Water purity, trace metal analysis (Fe, Pd, Cu, U) ● ● 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. 184 UK: Tel: +44 (0)1462 424700 • wpiuk@wpi-europe.com World Precision Instruments www.wpiinc.com Germany: Tel: +49 (0)30-6188845 • wpide@wpi-europe.com US: Tel: 941-371-1003 • sales@wpiinc.com
