When exposed to humidity in an oxidizing atmosphere hydrated uranium oxide grows as a secondary mineral on aged U3O8 and may incorporate the oxygen stable isotope signature of the water vapor into the secondary uranium oxide, as well as hydrogen and oxygen stable isotopes into any mineral hydration water. Because geospatial variation in δ2 H and δ18O values of atmospheric humidity and…

In this insightful interview, Tom Dockery, Senior Director of Client Delivery and Support at Picarro, shares his unique viewpoint on client delivery and support. With a depth of experience behind him, Dockery provides an inside look at the challenges, triumphs, and overall journey of his role…

Ammonia (NH₃) is the highest abundant alkaline gas in the atmosphere, and it is a major contributor to total reactive nitrogen in the environment and causes long-term climate change problems. NH₃ is also a hazardous pollutant with detrimental impacts on human health that demands strict control over personal exposure levels. High-precision quantification of NH_3…

In this poster, Picarro shares research and recommended best practices for using Picarro water isotope analyzers to measure highly enriched and depleted δ²H water isotope samples. These tips will be especially helpful for hydrological tracer studies and kinesiological applications. The experiments show how the Picarro water isotope analyzers’ Express Mode…

This poster highlights a case study on the impacts of wildfire emissions in Canada on the Carolinas and Virginia. It features some really interesting findings comparing the Picarro G2307’s formaldehyde measurements to those from the EPA National Air Toxics Trends Station (NATTS) Network. It shows that by correcting for drift over time, a lower detection limit and…

Anthropogenic emissions from traffic and industrial activities and their impact on air quality are a major concern in urban areas. The concentration of the air pollutants from these sources is typically measured with stationary air quality monitors, which are often limited in number. In addition, these stationary measurements often prove inadequate in representing the emission scenarios of…

Emissions from thousands of in-use heavy-duty diesel trucks were sampled at a highway and an arterial street location in the San Francisco Bay Area, spanning a time period when use of diesel particle filters (DPFs) and selective catalytic reduction (SCR) increased rapidly. At the highway site where a diverse mix of trucks is observed, SCR systems on 2010 and newer engines reduce emitted…

Ammonia (NH₃) is typically present at higher concentrations in indoor air (∼10–70 ppb) than in outdoor air (∼50 ppt to 5 ppb). It is the dominant neutralizer of acidic species in indoor environments, strongly influencing the partitioning of gaseous acidic and basic species to aerosols, surface films, and bulk water. We have measured NH₃ emissions from humans in an…

We blogged previously about carbon sequestration and its a topic we watch closely. You may have read that earlier this week Saskatchewan approved plans for a commercial-scale carbon capture and sequestration (CCS) project. The Canadian province is among the first in the world to push forward with a really big CCS effort. The province greenlighted plans by power-provider SaskPower to…

I'm Nabil Saad and I'm a senior applications scientist at Picarro. I'll be blogging periodically about applications development around stable isotopes. There is a lot going on. So last month we delivered a brand new Picarro Combustion Module-Cavity Ring-Down Spectrometer (CM-CRDS) to the U.S. Customs and Borders Protection (…

Today the World Economic Forum announced that Picarro had been selected as a Technology Pioneer 2012. This is a tremendous honor and a proud day for all Picarro employees! The World Economic Forum is one of the most prestigious collaborative problem-solving organizations on the planet…

Final Exam Question #17 – What is a Picarro and how does it work?

As a Picarro sales engineer, I spend much of my time discussing our products with university professors, researchers, post-docs, Ph.D. candidates, grad students, etc. Picarro is connected to academia but we hadn't really connected yet with undegrads - the future scientists. That's changing. 

We have over time gotten a fair number of queries related to whether our CRDS analyzers can be used to determine whether an animal is corn-fed or grass-fed, and where that animal comes from. Consumers, restaurateurs, and food companies increasingly care a lot about what goes into the mouths of the meat they sell and whether that meat is local or from Brazil or Texas or wherever. Which is…

One of the most interesting things we product managers get to do at Picarro is spend time in the field with customers learning how they use our analyzers.  This way, we get to experience firsthand the challenges of doing science outdoors in remote locations - challenges like dealing with unpleasant wildlife (for example). Studying fluxes of greenhouse gases in the environment is…

Rarely does a month go by without another major meat recall. In this case, the meat in question was shipped from Italy to Canada and contained dangerous levels of Lysteria bacteria.  And it was cooked, not raw, meat. We hope that no one gets…
