Measuring soil carbon fluxes in a remote North American temperate mountain ecosystem


At Picarro, we often write about our products and applications. But we much prefer to read how our customers are using them in their research projects. Cole Brachmann, Guillermo Hernandez Ramirez, and David Hik with the Departments of Biological Sciences and Renewable Resources at the University of Alberta, Edmonton, have taken time to pen a description of their summer soil flux study. Thanks to all three for sharing their experience.

Picarro Introduces an Oxygen Gas Concentration and Isotope Analyzer

We've just introduced the Picarro G2207-i gas concentration and isotope analyzer for atmospheric applications including oxygen monitoring to identify the biogeochemical process involved in the carbon cycle. The analyzer combines high precision and low drift O2 concentration measurement with δ18O analysis in ambient air.

Introducing the Picarro PI2114 Hydrogen Peroxide Analyzer

We've just introduced the new Picarro PI2114 hydrogen peroxide gas concentration analyzer for GMP pharmaceutical manufacturing. You can learn more about it and download a data sheet at www.picarro.com/pharma. Here's a short description about the applications it addresses and the benefits and advantages of using it.

Guarantee the Purity of Organic Coconut Water with a Picarro CM-CRDS System

The production, sale, and distribution of coconut water is a multibillion-dollar global industry. Given the increase in preference and consumption of pure ‘organic' coconut water, producers are challenged to ensure product purity and maintain customer confidence. This demands an absolute method for producers to distinguish between ‘pure' coconut water, without added sugar, and ‘adulterated' water, with added sugar. The Picarro Combustion Module Cavity Ring-Down Spectroscopy (CM-CRDS) System is a low-cost, easy-to-use, accurate, and precise solution to identify the addition of C4 sugars (adulteration), based on the carbon isotopic (δ13C) composition of coconut water.

The Picarro GasScouter™ Mobile Analyzer goes to the ends of the Earth

We introduced the Picarro GasScouter™ mobile gas concentration analyzer to make it easier for scientists to perform high-precision measurements of carbon dioxide (CO2) and methane (CH4) in the world’s most challenging, remote environments. And scientists at the University of Copenhagen are seizing the opportunity to use the new-generation, light-weight, portable, battery-powered cavity ring-down spectroscopy (CRDS) gas concentration analyzer at both ends of the Earth.

Methane Emissions Estimate from Airborne Measurements in Uintah Basin

Anna Karion and Colm Sweeney

The American Geophysical Union has accepted an article for publication, Methane emissions estimate from airborne measurements over a western United States natural gas field, from lead authors Anna Karion and Colm Sweeney based on joint research by the Cooperative Institute for Research in Environmental Sciences (CIRES), the Natio

ClimateWire 3-Part Series on Natural Gas

ClimateWire

Stephanie Paige Ogburn of ClimateWire has written an in-depth 3-part series on natural gas that makes a compelling case for accurately measuring leaks from production to delivery.

Tests of the Picarro G5101-i Analyzer (Professor Rich Farrell)

In the first post of this series, I noted that Gloria Jacobson, Picarro product manager for greenhouse gas analyzers, had been discussing Picarro G5101-i analyzer test results with several scientists, and would provide more detailed information in a series of posts.

Field Tests of the Picarro G5101-i Analyzer

Gloria Jacobson, Picarro product manager for greenhouse gas analyzers, has been very busy lately. As the picture shows, she has been testing products in nearby marsh lands. In addition, she has discussed field tests with independent scientists, and attended several conferences in the U.S. and China. Over the next few weeks, she will be sharing her insights through a series of blog posts.
