The Ozone Has Its Day

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.

Could Hospital Sterilization Be Making Employees Sick?

In the battle against infectious disease, sterilization of medical instrumentation is one of the most important steps to keeping patients safe. Various methods are used in modern hospitals to sterilize equipment, from steam sterilization to hydrogen peroxide. However, the most effective tool remains Ethylene Oxide Gas (EOG or EtO), a highly reactive gas that can penetrate most surfaces of the object being sterilized without destroying it. EOG is critical to keeping endotracheal intubation tubes used in ventilators for COVID-19 patients from spreading bacterial infection.

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).
