o2 Sensor for real-time analysis Fluorescence-based optical sensor system BIOS EN S I NG The new oxygen sensing system measures fluorescence lifetime, phase and intensity, using LED excitation and photodiode detection with filterbased wavelength selection. The system is simple to set-up and control. The compact, self-contained unit makes it invariant to fiber bending and stray light. It also has a wide dynamic range of optical intensity, as well as low optical and electronic crosstalk, and low drift and phase noise. When stability and sensitivity to drift are important in your oxygen sensing experiment, this unit is ideal. It is perfect for applications where sample set-ups must be left undisturbed for long periods of time. three coatings available for probes and patches The optical sensors consist of transducer materials, applied to the tips of optical fibers or to substrates such as patches or cuvettes, which change optical properties in response to specific analytes in their immediate environment. oXY–The standard oxygen sensor designed for monitoring oxygen partial pressure in gas and aqueous solutions is a fiber optic fluorescence probe with a proprietary oxygen sensing coated tip. HioXY–Designed for monitoring oxygen partial pressure in nonaqueous vapors and solutions. The sensor coating chemistry is compatible with oils, alcohols, and hydrocarbon-based vapors and liquids. FLOX is a device for measuring fluorescence lifetime, phase and intensity. It uses LED excitation and photodiode detection with filter-based wavelength selection for easy experimental set-up and control. Because the unit is self-contained, it is invariant to fiber bending and stray light, and has a wide dynamic range of optical intensity as well as low optical and electronic crosstalk, and low drift and phase noise. FLOX is especially useful for oxygen sensing applications where stability and sensitivity to drift is important and where sample set-ups must be left undisturbed for long periods of time. ● Fluorescence-sensing detector for optical sensors, a viable alternative to traditional chemical sensing devices ● Self-contained, benchtop system–invariant to fiber bending or stray light ● Affordable–Half the cost of comparable phase measurement systems ● Excellent stability, extremely low drift and phase noise ● Simple calibration, setup and control FoSpor–A new generation of highly sensitive sensor coating can be used for monitoring traces of oxygen in gas and liquids. The oxygen sensor probes are low-power and offer high sensitivity, reversibility and stability, ideal for remote monitoring. The thin coating on the probe tips consumes no oxygen, allowing for continuous contact with the sample. They are ideal for viscous samples and are immune to interference caused by pH, ionic strength or salinity fluctuations or biofouling. introDuctorY price FLoX-patcH Non-Invasive Oxygen Monitoring Kit, including phase measurement system, temperature probe, 4mm HIOXY sensor patches FLoX-proBe In Situ Oxygen Monitoring Kit, including phase measurement system, temperature probe, and HIOXY O2 sensor FLOX software displays oxygen measurements on a connected PC. 62 World Precision Instruments UK: Tel: +44 (0)1462 424700 • wpiuk@wpi-europe.com www.wpiinc.com Germany: Tel: +49 (0)30-6188845 • wpide@wpi-europe.com US: Tel: 941-371-1003 • sales@wpiinc.com
