Ultraportable Multi-Gas Carbon Emissions Analyzers (CH4, CO, CO2, H2O)

The Multi-gas Carbon Emissions Analyzer (CH4 , CO, CO2, H2O), or MCEA, is capable of simultaneous measurements of methane, carbon monoxide, carbon dioxide, water vapor from ppb to percent (%) levels.  The MCEA is simple to use, sensitive, and rugged which makes it ideal for high precision atmospheric monitoring, continuous emissions monitoring, industrial process control and compliance monitoring applications.

In addition, the MCEA is now available in LGR’s “ultraportable” package (U-MCEA) which is compact, crushproof and travels anywhere. Small enough to be carried on-board aircraft (TSA approved), the U-MCEA offers opportunities to measure all of the target gases (CO, CO2, CH4 and H2O) anywhere.

The MCEA and U-MCEA offer ultrafast response to provide users with real-time data and the opportunity for closed-loop feedback control for continuous online optimization of processes such as furnaces (steel, glass manufacturing), incinerators, chemical production plants, petrochemical refineries and other high temperature processes.

Like all LGR analyzers, measurements are based on high-resolution absorption spectra which allows the instrument to accurately correct for water vapor dilution and absorption line broadening effects and thus to accurately report gas concentrations on a wet and dry mole fraction basis directly without drying or post processing. Furthermore, unlike conventional technologies (including photoacoustic, FTIR and NDIR techniques), LGR’s high resolution laser-based method provides accurate “species specific” measurements without cross sensitivity.

LGR’s patented technology, a fourth-generation cavity enhanced laser absorption technique, has many advantages (simpler, easier to build, rugged, sensitive) over older, conventional cavity ringdown spectroscopy and other absorption techniques. As a result, LGR Analyzers provide highest performance at low cost.

LGR Analyzers have an internal computer (Linux OS) that can store data practically indefinitely on a hard disk drive and send real time data to a data logger via the digital (RS232), analog or Ethernet outputs.  In addition, LGR analyzers may be controlled remotely via the Internet. This capability allows the user to operate the analyzer using a web browser anywhere.
