The Picarro G2205 gas concentration analyzer provides precise, real-time measurement of hydrogen fluoride (HF) and water (H2O) vapor at parts-per-trillion (ppt) sensitivity with negligible drift for atmospheric science and air quality applications. This manual provides safety, contents, overview, installation, operation, log messages, file management, calibration, troubleshooting…
Picarro Autosampler - Automatically draws water from 2mL vials and delivers from 1uL to 10uL of water into your vaporization unit of choice. The vapor content is then sent to our CRDS for analysis of the isotopic content Readily integrated with our water isotope analyzers (L2120-i or…
The Picarro G5102-i isotopic and gas concentration analyzer enables measurements of site specific and bulk δ15N in N2O. It is an ideal solution for discerning and measuring the source of N2O emissions real-time in the field or through grab-sample measurements in the lab. The isotopomers of N2O can be used to probe sources and sinks…
Particulate matter affects more people than any other ambient air pollutant, leading to increased risk of cardiovascular and respiratory diseases. Levels of PM10 and PM2.5 in the developing world, especially southeast Asia and the Indian subcontinent, routinely exceed World Health Organization guidelines, often by a factor of 10 or more. Despite their importance to poor air…
Photosynthesis is a complex process that consumes carbon dioxide and water to produce oxygen and glucose. Studies to investigate leaf-level photosynthetic activity have been conducted using systems that control certain parameters such as light intensity or partial pressure of CO2. For instance, the LI-COR LI‑6800 Portable Photosynthesis System enables the user to control and measure light,…

FRANCE / RUSSIA — With a large percentage of its area covered by forest (800×106 hectares) and huge stocks of carbon (roughly 320 gigatons), Siberia is a…
Jim Butler, Director, Global Monitoring, NOAA Earth System Research Lab
BOULDER, CO — According to their website, the Global Monitoring Division of the National Oceanic and Atmospheric Administration’s Earth System Research Laboratory (NOAA/ESRL/GMD) “conducts sustained observations and research related to source and sink strengths, trends, and global…
Integrated Non-CO2 Greenhouse Gas Observing System
CABAUW, NETHERLANDS — While carbon dioxide (CO2) currently contributes to two-thirds of anthropogenic radiative forcing, the effects from other greenhouse gases (GHGs), such as methane and nitrous oxide, remain largely uncharacterized and could significantly impact the future of global climate change.…
Professor Jeffrey Richey (University of Washington) and colleagues probe carbon cycling on the Amazon
This story starts more than 20 years ago when Professor Jeffrey Richey’s research group started to consider the importance of the tropics, and particularly, the Amazon basin, to the global carbon cycle. With the “missing sink” of the global carbon…
Picarro returns to Semicon West with real-time airborne molecular contamination monitoring systems for semiconductor fabs applications
Santa Clara, CA — June 28, 2019 — Picarro Inc., a leading provider of trace gas analyzers for a variety of air monitoring applications…
This application note outlines the configuration and use of the Picarro G2201-i dual carbon (CO2 & CH4) isotope analyzer to differentiate between C3 and C4 respiration sources at a transitional agricultural experiment in southern Sweden.
Flood-irrigated agricultural soils can be a significant source of the greenhouse gases (GHG) carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) (Linquist et al. 2011, Oertel et al. 2016). As these ecosystems are typically characterized by high spatial and temporal heterogeneity, continuous trace gas measurements are needed to better detect patterns and quantify net ecosystem…
