The TFS from Envent Engineering Ltd is an all-optical analytical platform using a TFS (tunable filter spectrometer) sensor powered by MKS Instruments – Precisive. Offering a GC like speciation at unparalleled speed (<5 sec); the TFS requires no carrier gas and accurately measures the BTU Heating Index and Wobbe Index. It uses infrared absorption to measure methane, ethane, propane, butanes pentanes, carbon dioxide and % level H2S.
