LGR’s Methane/Acetylene Analyzer is the world’s

most advanced instrument for simultaneous

measurements of methane, acetylene and water

vapor. Quite simply, no other analyzer provides

higher performance.

Measurement of acetylene can be extremely useful

in tracer studies of landfills and other scientific

studies. For these tracer studies, the ability to

report with high sensitivity and accuracy over a

very large dynamic range is imperative. The MMA

is extraordinarily simple to use, requires very low

power and is extremely rugged which makes it

ideal for field studies. 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 C2H2 on a dry mole fraction

basis directly without drying or post processing.

Furthermore, LGR’s new “Extended Range” option

provides accurate measurements at levels up to

10% (without dilution) without reducing precision

and sensitivity at typical ambient levels.
