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.
