Methane/Acetylene Analyzer (CH4, C2H2, H2O)


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.

LGR’s new “Enhanced Performance” series incorporates proprietary internal thermal control for ultra-stable measurements with unsurpassed precision, accuracy and drift as validated at several leading labs and monitoring networks in Europe, Asia and the US. Moreover, only LGR’s analyzers provide reliable guaranteed measurements at mole fractions more than 1000 times ambient levels.

LGR’s patented technology, a fourth-generation cavity enhanced absorption technique, has many advantages (simpler, easier to build, rugged) over older, conventional cavity ringdown spectroscopy (CRDS) techniques. As a result, LGR Analyzers provide higher performance at lower 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 Internet access is available. Furthermore, remote access allows full control of the instrument and provides the opportunity to obtain data and diagnose the instrument operation without being on site.
