Precisive® TFS™ Tunable Filter Spectroscopy

Precisive® TFS™ Tunable Filter Spectroscopy

Natural Gas Quality, C1-nC6 Hydrocarbon Composition, and BTU/Wobbe Monitoring

The MKS Precisive® product platform of innovative optical analyzers based on Tunable Filter Spectroscopy (TFS™) provides real-time gas analysis in the natural gas and hydrocarbon processing industries, including refineries, hydrocarbon processing plants, gas-to-power machines, biogas processes and fuel gas transportation and metering, while delivering customers a substantially lower total cost of ownership. Precisive® TFS™ can be utilized from UV (Ultra-Violet) through IR (Infra-Red) spectral regions. The Precisive® TFS™ sensor platform has been on the market since 2008 with more than 2500 systems deployed.

Precisive® optical sensors are the first widely deployed hydrocarbon composition monitors to feature real-time unattended analytics with hydrocarbon speciation capability equivalent to traditional Gas Chromatography (GC) instruments yet, with much lower cost of ownership.

Now a part of MKS Instruments, the Precisive® TFS™ sensor platform will be further developed for trace/ppm through bulk/% applications where a multi-component, low-maintenance, stable analytical sensor-transmitter is required that is well positioned between traditional NDIR (Non-Dispersive Infrared) and laboratory-grade FTIR (Fourier Transform Infrared).
