Measure Methane (CH<sub>4</sub>) and Ethane (C<sub>2</sub>H<sub>6</sub>)

Measure Methane (CH4) and Ethane (C2H6)

Picarro GasScouter™ G4302 Gas Concentration Analyzer

The Picarro GasScouter G4302 is a new-generation, light-weight, portable, battery-powered cavity ring-down spectroscopy (CRDS) gas concentration analyzer designed for science on the move. It is a perfect mobile solution for real-time methane emission source attribution in the world’s most challenging, remote environments.

  • High-precision ppb measurements of CH4 and C2H6 concentrations
  • Portable, lightweight (25 pounds), low power (35 W) backpack case
  • Built-in rechargeable Li-ion battery for up to 6 hours of continuous operation and seamless battery switching for uninterrupted measurement
  • Built-in WiFi for mobile operation with a tablet or smartphone in remote locations
  • Optional accessories for mobile soil flux systems and GPS

The GasScouter analyzer operates in two different modes: 1) Methane only mode to precisely measure trace levels of methane in the atmosphere and 2) Ethane/Methane mode to measure the ethane-to-methane ratio for determining the emission source. This makes it ideal for efficient, exact identification and quantification of methane gas from biogenic and anthropogenic sources, especially in remote locations. The GasScouter is also an excellent instrument for soil flux measurements. The sampling system has an integrated pump. It can be used for continuous field mapping or in closed-loop configurations for soil chamber studies, which makes it a versatile analyzer for field applications.

Picarro patented CRDS technology enables an effective measurement path length of up to 20 kilometers in a compact cavity, which results in exceptional precision and sensitivity from a small-footprint analyzer. A meticulously designed small optical cavity incorporates precise temperature and pressure control. The result is an analyzer that delivers a best-in-class combination of precision, accuracy, low drift and ease-of-use.
