Unrivalled performance for the most demanding oxygen process monitoring

A real time optical analyzer utilizing the SpectraScan offers a breakthrough capability in the continuous analysis of light hydrocarbons C1-C6. A faster, less complex and more reliable technology than the gas chromatograph techniques traditionally used in light hydrocarbon applications, the SpectraScan is a genuine game-changer in gas analysis. With innovative infra red absorption spectroscopy using state of the art spectral scanning coupled with chemometric based data processing, the SpectraScan delivers exceptionally high accuracy, low cross sensitivity and a very fast speed of response.

A no-compromise solution

A flow-through cell uses a patented spectrometer design for a high quality optical measurement, resulting in a high signal-to-noise ratio which gives a stable and accurate measurement. The SpectraScan achieves a precise separation of the sample into constituent components using an advanced Tunable Filter Spectroscopy Analysis algorithm. Optimized with cross interference modeling, spectral non-linearity compensation and peak shifting compensation, this breakthrough chemometric algorithm delivers industry-leading interference compensation with a permanent span calibration, low cross-interference, high baseline stability and a linear response throughout the scanning range. Wavelength scanning is achieved by a tunable band-pass filter, with a unique design that enables simultaneous scanning of selected wavelength bands for gases including Methane, Ethane, Propane, iso-Butane, n-Butane, Propylene, Ethylene, and many more.
