Portable FTIR Gas Analyzer - ToronFTIR™ G12000
ToronFTIR™ G12000 is a portable FTIR gas analyzer built for continuous emissions and VOC monitoring at fixed pollution sources such as coal-fired power, steel, cement, and waste-incineration plants. The instrument reads the infrared fingerprint of a flowing gas sample and quantifies dozens of components at once, from combustion gases like SO₂, NO, and CO to a wide list of volatile organic compounds. A heated, corrosion-protected sample cell lets the analyzer work directly on hot, humid, and corrosive flue gas without losing reactive or condensable species.
The ToronFTIR™ G12000 pairs the analyzer with a full-process heated sampling system and a flue-gas pretreatment stage, so the sample reaches the cell at temperature and free of dust. A room-temperature DTGS detector removes any need for liquid-nitrogen or thermoelectric cooling, which keeps field operation simple. Battery power, a portable workstation, and a transport case make the system practical for stack surveys, mobile audits, and emergency response away from mains power.
The analyzer measures more than fifty gas components as standard and accepts a customized gas menu on request. Software handles multi-point calibration, dry and wet concentration conversion, temperature and pressure compensation, and automatic correction of cross-interference between components. Continuous logging, trend charts, spectral replay, and Excel export give operators a full record for reporting and later review.

Theory and Method
Fourier transform infrared gas analysis identifies and quantifies gases by the way their molecules absorb infrared light. Each gas absorbs at characteristic wavenumbers set by the vibration of its chemical bonds, so a mixture produces a combined spectrum that the software separates into individual components. The ToronFTIR™ G12000 records the full spectrum in a single measurement rather than scanning one wavelength at a time, which lets it report many gases at once and repeat the measurement several times each second.
At the core sits a Michelson interferometer. A beamsplitter with moisture-proof windows divides the infrared beam into two paths that reflect off a fixed and a moving mirror. Recombining the beams produces an interferogram, and a Fourier transform converts it into an absorbance spectrum. The Beer-Lambert relationship then links absorbance to concentration: a longer optical path and higher absorbance mean more molecules in the beam. A folded path of at least 4.5 meters inside a sub-1-liter cell gives the sensitivity needed for low-level pollutants.
Sample handling decides accuracy as much as the optics. Reactive and condensable gases such as HCl, HF, NH₃, and water stick to cold surfaces or drop out as the sample cools, which biases the reading. The ToronFTIR™ G12000 keeps the probe, sample lines, and cell above 180 °C along the entire path, so the sample stays in the vapor phase from stack to detector. Anti-corrosion coatings protect the cell and reflector from acidic flue gas during extended field runs.
