Methane Analyzer (CH4, H2O) - Ultraportable Overview

LGR’s new ground-breaking Ultra-Portable Methane Analyzer (UMA) reports measurements of methane and water vapor simultaneously in a package that is compact and crushproof. Small enough to be carried on-board aircraft (TSA approved size) and requiring only 60 watts, the UMA travels anywhere, initiates data collection within 100 seconds after power up, and opens up new opportunities to accurately and precisely measure methane with ease.

As with all LGR instruments, the UMA is simple to use which makes it ideal for field studies, compliance monitoring, leak detection (e.g., natural gas, coal seam gas, coal bed methane), air quality studies and soil flux studies, and wherever fast, accurate and precise measurements of methane are needed.  In addition, as with all LGR instruments, the UMA reports fully resolved absorption lineshapes in real time which allows LGR instruments to accurately correct for water vapor dilution and absorption line broadening effects accurately and thus to report CH4 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 LGR capability.  Moreover, only LGR’s analyzers provide reliable guaranteed measurements at mole fractions much greater than 1000 times ambient levels.

LGR’s patented technology, a fourth-generation cavity enhanced absorption technique, has many advantages (simpler, easier to build, rugged, less expensive) 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 access and 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.
