A Universal and Objective Measurement and Tracking Tool for Carbon Credits
As regional, national and international trading exchanges for carbon credits undergo accelerated expansion, the current approach of "account and extrapolate" must be replaced inevitably by the rigorous discipline of "measure and monitor." Fortunately, the appropriate technology already exists. In this whitepaper, we describe how a portable quantitative analyzer based on WS-CRDS technology provides a universal GHG accounting tool for this purpose — delivering the proven world-class performance that's used at leading laboratories like NOAA and the Max Planck Institute, together with the turnkey operational simplicity that enables its use by semi-skilled field technicians.
WS-CRDS - A Universal Instrument for Precision Measurement of GHGs
Picarro WS-CRDS-based analyzers are the first GHG monitoring instruments to combine state-of-the-art performance with simple ease of use. In this whitepaper we describe how and why these compact, portable WS-CRDS analyzers provide turnkey operation together with sensitivity and precision at the parts per billion level, no interference between other gas components, and no need for frequent calibration. Performance and applications data are presented for CO2, CH4 and H2O.
Simple, Real-Time Measurement of Stable Isotope Ratios in H2O and CO2
Picarro WS-CRDS-based analyzers are the first instruments to provide simple, turnkey access to stable isotope ratios with sensitivity and precision better than or equal to the IRMS (isotope ratio mass spectrometer) systems traditionally used in stable isotope labs. This in-depth whitepaper explains how and why WS-CRDS technology opens the door for widespread exploitation of stable isotope studies in fields such as carbon/water cycle research, GHG (greenhouse gas) monitoring, animal migration, total organic carbon measurements, and human metabolism. Performance data (δ18O, δD, and δ13C) are discussed for applications involving CO2 and H2O (both liquid and vapor-phase direct sampling).
