As regulators implement new air quality standards targeted at commercial sterilization and chemical industries, there is a growing need for precise, turn-key monitoring systems that are proven to operate long-term at the fenceline and in communities. In this new blog, Dave Miller explains how Picarro is continuing to address this need with a recent addition to its family of ethylene oxide monitoring solutions.
Indoor air quality is highly correlated with the health of employees in workplaces where toxic gases are present. Companies using EtO need to adopt new monitoring approaches that provide a fast response and are specific and sensitive to low concentration levels of fugitive emissions. This new blog describes how to better monitor fugitive EtO emissions in the workplace with Picarro EtO monitoring solutions.

Ethylene oxide (EtO) is frequently used in sterilization processes, however, hazards exist from exposure to this toxic gas. This blog reviews the evolving federal rules governing source and fugitive emissions and highlights how Picarro and partners are enabling companies to monitor emissions and generate the defensible data they need to comply.

Picarro is proud to support important climate science. We are a partner of the DEEPICE project, an innovative training network in instrumentation, ice core analysis, and glaciological and climatic modelling. For their new European collaboration, we’re excited to support training schools and host an intern to assist in the development of analytical methods for ice core measurements that will answer key questions about the impact of large climate shifts on the Antarctic ice sheet.

Surrogate Gas Validation: A Safer, Easier Way to Validate Measurements of Hazardous, Corrosive, and Reactive Trace Gases
High-precision trace gas measurements are required for a range of environmental research questions and for many industrial applications. However, hazardous, corrosive, and reactive gases can be difficult to trace, and the accuracy of standard gas concentrations can be unreliable. To solve this problem, Picarro has developed a method of surrogate gas validation for ammonia, hydrogen chloride, hydrogen peroxide, hydrogen fluoride, and formaldehyde.

Investigating the Effect of Climate Change on Ecosystems by Imitating Future Environmental Conditions
To investigate how plant growth will be affected in the future, ecologists and plant biologists have setup Free-Air Carbon dioxide Enrichment (FACE) facilities in various ecosystems around the world that imitate elevated atmospheric carbon dioxide concentrations. A Picarro G2508 is being used at a FACE facility in Germany to investigate the response of a semi-natural grassland to changing environmental conditions.

Google “Laser-Based Diagnostics of Diamond Synthesis Reactors” and one of the first things you’ll see is Ed Wahl’s Stanford PhD thesis from 2001. Back then he was applying Cavity Ring-Down Spectroscopy (CRDS) to measure absolute CH3 and CH radical concentrations and temperatures in a hot-filament CVD (HFCVD) reactor. Today, he’s

Hydrogen peroxide has a long history as a pharmaceutical sterilizer at high concentrations, and the claim by these manufacturers is that extremely low levels of hydrogen peroxide (10-20ppb or 0.01ppm) will attract and kill viral particles while not impacting human health. Instead of just treating air as it returns, these solutions seek to keep a constant low level of hydrogen peroxide in all habitable areas of a building.

Gas operators are increasingly being challenged to reduce methane emissions, and to do so in a continuous, verifiable way. This challenge at its most extreme has some cities recently banning natural gas in new construction. Further, as the infrastructure ages, gas operators face challenges in managing budgets and unplanned work due to an accelerating rate of growth in the number of leaks emerging from leak-prone pipe. These pressures are driving the need to manage gas assets as cost-effectively as possible.

September 16 is World Ozone Day. This year celebrates 35 years of the Vienna Convention and 35 years of global ozone layer protection. In honor of World Ozone Day, we’re taking a look back over the last decade at some of the important work customers all over the world have done using our gas analyzers to measure greenhouse gases in support of ozone research.

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

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!
