Quantifying Ethylene Oxide, an historically essential, but hazardous gas

Developing a regulatory and industrial mitigation response to ethylene oxide emissions (C2H4O / EtO) poses a centuries old scientific challenge – how do we fix a problem that we cannot measure? The understanding of infectious agents has come a long way since Ignaz Semmelweis first introduced, in 1850, the practice

A fully integrated solution for soil flux measurements in flooded terrain

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!

A Pioneer in Advancing Measurement Technologies to Assure Biologic Drug Stability and Efficacy

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).

Real-Time Indoor Air Measurements of Ammonia Part 1: iCHEAR

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.

Quantifying carbon dioxide and methane efflux in the Mekong Delta in Cambodia and Vietnam

At Picarro, we enjoy hearing how research groups are using our systems in their projects. Christopher Hackney and Daniel Parsons from the University of Hull (UK) are working on a series of UK Research Council and Newton Fund funded projects(e.g. http://www.stelar-s2s.org) with partners from the Universities of Southampton, Exeter (UK), Illinois (USA) and Can Tho (Vietnam) and the Southern Institute of Water Resources Research (Vietnam)on the Mekong Delta in SE Asia.

O2, CO2, and Chlorophyll Walk into a Leaf...

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.

VHP of just 30 ppb can oxidize and ruin pharmaceuticals

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.

Monitoring isotopic composition (δ18O, δD) of water vapor, precipitation and snow surface in the Antarctic region.

Anna Kozachek of the Arctic and Antarctic Research Institute (AARI), Saint Petersburg has taken time to write a description of her team’s use of the Picarro L2130-i and L2120-i during the Antarctic Circumnavigation Expedition (ACE) project. The main goal of the expedition was to circumnavigate Antarctica, performing oceanographic and meteorological observations along the route as well as terrestrial observations on the sub-Antarctic and Antarctic islands. Learn more about their setup and overall findings.

Investigating Experimental Priming Effects in Anaerobic Decomposition of Peats from Discontinuous Permafrost in Canada

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.

Measuring Small Volume Gas Concentrations with the Small Sample Introduction Module

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.
