LGR’s Greenhouse Gas Analyzer is the world’s

most advanced instrument for simultaneous

measurements of methane, carbon dioxide and

water vapor. Quite simply, no other analyzer

provides higher performance.

The GGA 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 GGA 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

and CO2 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.
