Portable water vapor isotope analyzer

Portable water vapor isotope analyzer(δ²H,δ¹⁸O, H₂O)

Ultraportable Water Vapor Isotope Analyzer

2015 In the year,LGR (currently under ABB Canada)We have launched a new portable water vapor isotope analyzer (UWVIA), which adopts a portable box design, reducing volume, weight, and improving portability. It is suitable for various measurement carriers, such as cars, airplanes, ships, unmanned aerial vehicles, and single person human carrying.UWVIAapproveIn situ high-frequency continuous measurement of δ under conditions of wide range variation in water vapor concentration²H,δ¹⁸OandH₂OMole fraction. By utilizing UWVIA, it is possible to achieve atmospheric analysis-The high-frequency measurement of water isotopes in the vegetation interface layer provides convenience for researchers to understand water vapor flux at the ecosystem scale, and is of great significance for fitting water vapor movement and predicting climate change. By using a water vapor isotope standard gas generator, it is possible to calibrate the nonlinearity and drift of the analyzer.
