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.
This is a real-time optical analyzer capable of performing compound speciation or separation which previously could only be performed by Gas Chromatograph (GC) analyzers. Using a unique wavelength-sweeping tunable filter spectrometer, fast update rates down to 1 second intervals are executed for full compound speciation and detection of the customer specific compound set. Sampling is a flow-through type, suitable for a continuous, on-line, unattended operation. The Precisive Trace Hydrocarbon/VOC Analyzer does not require carrier gas, fuel gases or on-site calibration gases.
