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.

Picarro technology helps PG&E survey 5200 gas lines in Yolo County

Picarro Surveyor Leak Detection

Picarro's partnership with PG&E continues to make headlines. Using Picarro technology, PG&E is able to perform a precision survey and maintenance operation on 5200 gas lines in Yolo county that would normally take four months in only two weeks.

Running your Picarro GasScouter and eosAC Off-Grid

G4301-GasScouter

Gas analyzers have become increasingly more precise over the past 10 years with the adoption of laser-based sources and ultra-long path length optical cells. However, usually this has been at the cost of power consumption, making them difficult to easily deploy in the field, especially off-grid.

Video: Advanced Technology Spots Gas Leaks

If you saw one rolling through the neighborhood, you might mistake it for a Google maps car, but for more than a year and a half, PG&E has been cruising for gas leaks, using Ford Explorers that are actually super-sensitive, gas detection vehicles. (KGO-TV)

Arctic Water and Carbon Isotope Cycles from the USCG Icebreaker Healy: Chukchi Sea, Alaska July 2016

Ice Breaker Healy

The hydrologic and carbon cycles in the Arctic are currently changing in conjunction with climatic transitions. This includes changes in sea ice extent and thickness, Arctic Ocean pH, and patterns of primary productivity and food web dynamics. Additionally, sea ice related changes in evaporation processes are influencing winter and summer precipitation regimes and broader scale climatic patterns. For example, Arctic vortex shifts allow more Arctic air to reach lower latitudes, which can result in more frequent extreme weather events in the northeast United States.

A Wonderful Video Introduction to Stable Isotope Analysis for Food Safety

Concerns about food safety and food origins are increasing around the world as our understanding of the potential health risks of adulterated food grows and consumers become aware of the risks of fraudulent food products that have been diluted with lower quality substitutes. Picarro's technology is at the forefront of the fight against food adulteration. Our isotopic analyzers allow scientists and regulators to analyze food ingredients to determine whether the food is genuine and came from where its label says it came from.
