δ13C for methane (CH4)
Picarro G2132-i Analyzer
High-precision, real-time carbon isotope information from methane at ambient concentrations.
- Isotopic measurements with superb precision and stability for critical methane source identification
- Direct measurement of CH4. No sample drying or preparation required
- Field deployable: <26 kg, shock and vibration tested
- Less calibration, less maintenance, no consumables
- Equipped with ChemDetect™ to sense contaminants in samples
Distinguishing between various sources of CH4 can help in a number of ways, such as: identifying its origin in groundwater near a hydraulic fracturing well, monitoring fugitive methane emissions from a landfill, or teasing apart the biochemical pathways that produce and consume methane in wetlands. Each source of methane has a characteristic ratio of 13C to 12C. Knowing this ratio helps link methane to a particular local source. The Picarro G2132-i makes precise 13C/12C ratio measurements fast and easy. The stability of the analyzer enables these ratios to be determined in the field, for immediate source identification.
The analyzer comes equipped with ChemDetect™, a new layer of analysis that inspects the recorded spectra to find indications of other contaminating species. ChemDetect™ looks for distortions of the spectra that would indicate that another gas phase species is in the sample and might be affecting the results. ChemDetect™ indicates when a sample is more complicated, and perhaps more interesting, than expected.
