A Next-Generation Wide Dynamic Range Isotopic Water Vapor Analyzer for Next-Generation Water Cycle Research

An instrument platform for truly field deployable high precision stable isotope analysis in hydrological lines of inquiry including evaporation, precipitation, transpiration, and transport.

Greenhouse Gas Monitoring Made Simple

The Picarro G1301 has been designed specifically to focus on the needs of the atmospheric monitoring community and to serve as the backbone for greenhouse gas monitoring networks. 

 

Software-Based Method to Flag Water Samples Contaminated with Trace Organics Such as Methanol and Methane

ChemCorrectTM  is an innovative software system that provides researchers with an unparalleled level confidence in their isotopic water sample fidelity. It also allows researchers can reprocess their data to correct for the spectral irregularities caused by contamination.

Accurate Greenhouse Gas Measurements in Humid Gas Streams Using the Picarro G1301 Carbon Dioxide / Methane / Water Vapor Gas Analyzer

The Picarro G1301 three-species greenhouse gas analyzer for the first time permits accurate and precise greenhouse gas measurements in compliance with WMO inter-laboratory comparability standards without requiring dried sample gas. This white paper contains a technical explanation and how-to guide for correcting measurements taken with a Picarro G1301 Analyzer.

Learn how a Picarro Isotopic Water Analyzer can Provide δ18O and δD for Less than $2 per Sample

Picarro WS-CRDS isotopic analyzers offer significantly lower capital costs than traditional isotope ratio mass spectrometry (IRMS) instruments. There is also a dramatic difference in the operating costs of the two technologies, making WS-CRDS a very attractive option.

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).
