One of our most popular pairings for a fully integrated soil flux measurement solution is Picarro’s G2000 series analyzers with Eosense’s eosAC Flux Chamber and eosMX Multiplexer. In this application, we see how our G2508 greenhouse gas analyzer is used with Eosense’s eosAC automated chambers and a modified, insulated enclosure for continuous measurements in periodically inundated fields. We’d like to thank Dr. Whendee L. Silver, Ph.D. candidate Tyler L. Anthony, and the Ecosystem Science Division team at University of California, Berkeley, USA for their contributions in this deployment. Enjoy!

Tree methane (aka ‘Treethane’) emissions have been referred to as 'a new frontier in the global carbon cycle', (Barba et al., 2019) representing a field that is gaining rapid research momentum. Whilst this line of research is now my primary focus, it wasn’t always that way...

The year was 2008. The second wave of therapeutic biological products was just around the corner. By now it was known that many of these products were susceptible to oxidative damage by residual hydrogen peroxide left over after aeration of the aseptic processing equipment and barrier system. How sensitive these products were to low concentrations of residual hydrogen peroxide was difficult to assess because there were no obvious measurement systems capable of quickly, accurately and precisely measuring vapor phase hydrogen peroxide below a few hundred parts per billion (ppb).

The most effective and valuable new therapeutic products today are biologics, including peptides, proteins, and antibody-drug conjugates (ADCs), as well as cells, cell-derived products, and gene therapies. Many of these products are susceptible to oxidative damage by trace levels of hydrogen peroxide.

The hydrogen and oxygen isotopic composition of rainfall is influenced by a variety of climatic factors such as air temperature, amount and origin of precipitation.

Anyone who has watched a hummingbird frantically sip from a flower or feeder can appreciate how beautiful, hyperactive, and hungry these tiny birds are. It often seems that they are constantly on the move, fiendishly searching for and defending the flowers that contain the sugary nectar they depend on.

From the Arctic tundra to the tropics of Mexico, from Los Angeles to Long Island, Stephen Conley and the pilots and scientists at Scientific Aviation have tracked and measured air pollution throughout North America using their fleet of light aircraft.

In this second part of the 2-part blog series on Real-Time Indoor Air Measurements of Ammonia, we present a short summary of House Observations of Microbial and Environmental Chemistry (HOMEChem), part of the Indoor Chem Project (https://indoorchem.org/). Enjoy!

In part 1 of this blog series, we explore how iCHEAR used a Picarro G2103 analyzer to provide real-time measurements of ammonia emissions to separate the contribution of exhaled and dermally emitted pollutants. What proportion of human emissions do you think can be measured and what proportion remain “missing”? Read on.

There are not many countries in the world left where you can truly say that they are blessed with intact native tropical forests. Of course we all know about the Amazon, but if we have a closer look it becomes clear that even the ‘Green hell’ as the Amazon basin has been labelled, is heavily affected by humans.

In the following video series of 6 episodes, Eosense walks us through the pairing process using a G2508 five species, gas concentration analyzer with their eosAC soil flux chamber and gives a demonstration on how to process, analyze and export the data using their software.

The following study takes us through the voyage of the Polarstern ice breaker of the Alfred Wegener Institute in Germany.

When people speak about the Oktoberfest in Munich, it is most likely about beer, roasted chickens and the typical Bavarian lederhosen. But due to the huge area involved and the large number of visitors, it is also obvious that there will be some amount of greenhouse gas emissions.

As the research and development of renewable energy sources increases in momentum, it was great to have the opportunity to participate in the First European Photosynthesis Congress held at the Swedish University of Agricultural Sciences in Uppsala, Sweden.

As biologics have supplanted small molecules as the dominant focus for many leading pharmaceutical companies, robust manufacturing processes for isolators and RABS continues to be an evolving process. In this environment, as the need for significantly better VHP monitoring has grown quickly, Picarro H2O2 analyzers have increased in popularity.

Accelerated rates of warming and wildfires in northern regions of Canada will result in an extensive thaw of permafrost peatlands and peat plateaus. This could result in the potential release of greenhouse gases to the atmosphere. The Department of Renewable Resources at the University of Alberta, Canada have taken time to explain how they are using the Picarro G2201-I analyzer and Small Sample Introduction Module (SSIM) to further investigate if substrate addition “primes” peat decomposition.

The Picarro Small Sample Introduction Module (SSIM) is designed for processing small volumes of gas samples through a Picarro analyzer. Through a minor modification, we can now expand the functionality of the SSIM so that more accurate concentration measurements can be performed on both isotopic and concentration analyzers.

If you are attending the 2018 EGU General Assembly from April 9 to 13 in Vienna, Austria, we hope you’ll attend Picarro-authored oral and poster presentations.
