Ultraportable Methane/Acetylene Analyzer (CH4, C2H2, H2O)

LGR’s new Ultraportable Methane/Acetylene Analyzer (UMAA) reports measurements of methane, acetylene and water vapor simultaneously in a package that is compact, crushproof and travels anywhere. Small enough to be carried on-board aircraft (TSA approved size) and requiring about 60 watts (including pump), the UMAA offers opportunities to measure anywhere. As with all LGR instruments, the UMAA is simple to use which makes it ideal for landfill tracer studies, compliance monitoring, leak detection, air quality studies, process monitoring, and wherever measurements of methane, acetylene and water vapor are needed.

In addition, the UMAA reports and stores all measured absorption spectra which 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 without drying or post processing. Furthermore, LGR’s “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. Moreover, only LGR’s analyzers provide reliable guaranteed measurements at mole fractions greater than 100 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) and direct absorption 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. 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.
