The Precisive® 5-271 is designed specifically for on-line quality monitoring of syngas derived from a variety of fuels, including coal and biomass. It provides fast and accurate measurement of Calorific Value, Wobbe Index, and compositional information, including CO2 in a single, compact analyzer. Based on a unique Tunable Filter Spectroscopy (TFS™) platform from MKS, the analyzer directly measures the component concentrations and calculates gas property values based on widely-accepted ISO standards.
The Precisive TFS™ (Tunable Filter Spectrometer) sensor platform consists of a light source, a sample cell (for gases, liquids or solids), a wavelength separating element (spectrometer) and a photo-detector. The wavelength separating element "slices" the wavelength components of the broadband light source which then interacts with the sample molecules. Some of the wavelength components are absorbed and some are transmitted through without any absorption.
Precisive TFS™ Tunable Filter Spectrometers use an advanced spectral decomposition algorithm. The resulting spectrum is called absorption spectrum, which acts as "fingerprints" which are used to identify the sample components and/or quantify the composition of the sample.
