LGR’s Fast Methane Analyzer (FMA) provides

extremely precise measurements of methane

(CH4) and water vapor at up to 20 Hz. In

addition to accurately monitoring typical

ambient methane levels, the unprecedented

response of LGR’s FMA allows measurements at

high mole fractions (to 1000ppm with extended

range option) for applications including landfills,

peatlands and chamber studies.

The FMA is simple to use, low power and

rugged which makes it ideal for field and

air quality studies. The ability to measure all

gases quickly makes the FMA an excellent

choice for eddy covariance and chamber

flux measurements. In addition, analysis of

the measured absorption spectra allows the

instrument to accurately correct for water

vapor dilution and absorption line broadening

effects and thus to report CH4 on a dry mole

fraction basis directly without drying or post

processing. Furthermore, LGR’s new “Extended

Range” option provides accurate methane

measurements at levels up to 10% mole fraction

(without dilution) without reducing precision

and sensitivity at typical ambient levels - a

unique capability to LGR. For highest portability,

Analyzer (separate datasheet).
