The Precisive® TFS™ (Tunable Filter Spectrometer) can be utilized from UV (Ultra-Violet) through IR (Infra-Red) spectral regions. With the unique and patented ability to target specific spectral regions and simultaneously perform scanning within one or multiple regions with MTFS (Multiplexed Tunable Filter Spectroscopy).
Trace level ppm (part per million) impurity monitoring is possible in either the UV platform or mid-IR platform depending on the best signal:noise (S:N) and analytical robustness for the given application.
Bulk percent (%) level compositions from 0.1% (1000 ppm) through 100% is possible on upwards of sixteen (16) channels simultaneously in real-time spanning speciated hydrocarbons, CO2, NH3, H2O, H2S and other compounds.
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 (Figure 1). A 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. The resulting spectrum is called absorption spectrum (Figure 2), which acts as "fingerprints" which are used to identify the sample components and/or quantify the composition of the sample.
