MD TFS2 Hydrocarbon Analyzer

This system is an optical analytical device using a TFS (tunable fiter spectroscopy) infrared sensor.

  1. General Details

    It offers a multi-component gas analysis at high speeds. In addition to measuring methane, ethane, propane, iso-butane, iso-pentane and n-butane, n-pentane and n-hexane compositions, it also measures CO2 and H2S at the percentage level. The spectrometer uses tunable Fabry-Perot hardware that provides wavelength scanning combined with advanced spectral processing that provides feedback in as little as 1 to 10 seconds. Optional additional measurements can also be made for different applications such as ethylene, propylene and butene analysis. Sampling is carried out through a flowthrough cell that provides instant and continuous imaging. It does not require any carrier gas, fuel gas or calibration gas for analyses. The standard system configuration displays measurements up to 100% methane, 25% ethane, 25% propane, 10% butanes and 5% pentanes, 100% H2S and 100% CO2. Diatomic compounds such as nitrogen, oxygen and hydrogen cannot be measured directly; these compounds may be reported as a group of unmeasured inert gases.
