When isotopes are mentioned in the same breath as law enforcement, the first thought that comes to mind is likely an atomic weapons-based attack using radioactive isotopes and what security forces can do to prevent it. That’s certainly the most publicized association between these words.
Picarro Named World Economic Forum Technology Pioneer 2012 And Our (Modest) Plan to Change the WorldAugust 31, 2011 - 9:12pm — Michael Woelk
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.

Hi, there. I'm Kevin Cunningham and I am the product manager for isotopic carbon analyzers at Picarro. I got my PhD in laser spectroscopy (but don't hold that against me) so it has been thrilling to work at Picarro where laser spectroscopy has been applied to so many other fields. And, you may have noticed, we have been announcing some fantastic innovations lately and now its my turn. The new G2131-i isotopic analyzer improves the precision levels for δ13C measurements by 3X with a guaranteed specification of 0.1 per mil at 380 parts per million.

When I joined Picarro at the start of September in 2009, Cavity Ring-Down Spectroscopy technology for isotope analysis had only just been created. In short order CRDS was validated by researchers whose laboratories specialized in using isotope ratio mass spectrometers (IRMS), devices which were previously considered the state of the art.

A general topic that has been discussed on this blog is “truth in labeling”. In the case of food, falsifying a label can mean lying about where it came from for prestige (Prosciutto carefully crafted in Parma carries a much higher market value than a piece of Bulgarian salted pork), politics (sure, profits from cocoa in nation “X” are being used to support a genocide, but it’s far cheaper than actually supplying it from stable nation “Y), or lying about a process (profit margins can be significantly increased if you cut that Macadamia Nut honey with some corn syrup).

Prior to Picarro, I was on the academic path. I completed my PhD under the supervision of a brilliant scientist, then scored a post-doc position with a highly regarded researcher doing cutting-edge work that gained attention from the press (and also happened to be in Hawaii). But I rapidly discovered that I was not too gaga about the academic life. The grant writing process and being stranded on a proverbial island to do your work alone were not for me.
Introducing Simultaneous High-Precision C+D Analysis in One Integrated System: Deuterium and Carbon Isotope Analysis Made SimpleAugust 8, 2011 - 11:00pm — Nabil Saad
I've written a bit about using Picarro's Combustion Module for novel application methods and I wanted to let you know about a brand new product we are releasing - This is a CRDS analyzer that simultaneously measures stable isotope ratios of both carbon and its bound hydrogen directly from a combustion front-end. We're confident this new system is a significant advancement in capabilities for isotope measurements.
Introducing In-Line Organics Removal From Isotopic Water Samples: New Micro-Pyrolysis Technology TM from PicarroJuly 27, 2011 - 10:54am — Gregor Hsiao
In conversations with stable isotope researchers around the world a recurrent theme has been the problems caused by organics compounds in water samples, ranging from plant water extracts to alcoholic beverages. For laser-based spectroscopic analyzers like Picarro, certain organic compounds, mostly alcohols, have caused spectral interference which distorted the reported isotope ratio. We took the first step towards solving the problem last year with our ChemCorrectTM software, which flags, identifies and quantifies organic contamination.
Roof Gardens, Fluxes, Heat Islands and Water Quality: LDEO's NYC Project on the Impact of Green RoofsJuly 21, 2011 - 1:19pm — Gloria Jacobson
In a week when heat waves are sweeping the country, a post about green roofs seems appropriate. Environmentalists have long espoused putting plants on top of buildings as a way to improve air quality in cities and reduce the urban island heat effect. Sounds nice, but what are the real impacts of green roofs? Will they reduce runoff water into storm drains? Will they clean the runoff water? Will they cool the city? And will green roofs absorb or emit methane and other greenhouse gases.

As I write this, I’m sitting on a ski-equipped LC-130 Hercules cargo plane from the New York Air National Guard’s 109th Airlift Wing, flying over Greenland, having just taken off from the NEEM camp at 77°N latitude where the sun is up 24 hours a day.

I've got two simple yet evocative phrases for you. Wing pods. Unmanned Aerial Vehicles. Excited? We are. During late June, a team of top scientists from the NASA Ames Research Center deployed three Picarro analyzers as part of the The Railroad Valley Vicarious Calibration Campaign, a collaboration between the Japan Aerospace Exploration Agency (JAXA), and NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif. One of the analyzers was deployed in a wing pod of an Alpha jet which flew up to altitudes of 25,000 feet. Another was deployed in the nose cone of an Unmanned Aerial Vehicle.

Climate scientists can be divided into two large interactive groups: Experimentalists, who go out into the world and collect climate data (e.g., levels of carbon dioxide, methane concentration, seasonal temperature, snowfall rates, etc.); and Modelers, those who build computer simulations based on that data (called “climate models” by those in the know) to estimate how climate variables affect one another (e.g., does increasing CO2 increase temperature enough to melt polar ice caps that will raise sea levels so high that Miami will be the next Atlantis?).

The greenhouse gas carbon dioxide (CO2) is a product of human activities that use carbon-based fuels, such as home heating, cars, and manufacturing plants, to name a few. But CO2 also has many natural sources, such as soil, volcanoes and all living things that breathe. So a necessary question that should be asked by climate and citizen scientists alike is, “How do you know increases in CO2 are from human activity?”

We just launched a new Food Tracebility and Food Safety mini-site and our timing sadly coincided with a tragedy in this arena. As the unfolding details of the horrible E.coli outbreak in Europe have highlighted, everything is wrong with current food traceability legislation, testing and understanding.

The Malaspina Expedition may set the record for the most well-travelled Picarro analyzer. And we can't wait to see the science that emerges from this fascinating voyage. Here's the story. The research voyage marks the 200 Year Anniversary of the death of Alessandro Malaspina in 1810. Malaspina directed the first Spanish scientific expedition to circumnavigate the Earth.

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 sick.

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 definitely one of the areas where the full outdoor research experience is mandatory.

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 why we welcome the opportunity to discuss how stable isotopes can both determine if a cow has been grass-fed or corn-fed and, further, where that meat comes from.

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.
Stable Isotopes and Marijuana: How U.S. Customs and Border Control Uses Picarro for Cannabis AnalysisMay 3, 2011 - 9:59am — Nabil Saad
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 (CBP), which is part of the Department of Homeland Security. The initial purpose of the CM-CRDS was to smoke marijuana. No, really.

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.

Yet another article in PLoS One that uses stable isotopes to glean critical insights from fossils of long-dead animals. A mixed team including researchers from France, Thailand, Germany and Myanmar examined stable isotopes in the teeth of fossils of an extinct genus of horse called Hipparion found near the remains of a type of ape (a hominoid) to determine the nature of the environment when the creatures were alive.

The image you see here is Ed Wahl, the guy who runs all our QA and testing on analyzers posing as a proud papa with the first Picarro analyzer that we manufactured and shipped out of our brand new state-of-the-art facility. This one is going to the National Institute of Standards and Technology, a new customer we are very excited about. They set all sorts of standards for how things are measured in the U.S. and what's considered acceptable in the world of measurement. As many of you know, we're growing very quickly.

Several of us from Picarro spent a week in Vienna talking to scientists from all around the world. For those of us "manning the booth," conferences like EGU and AGU are both exciting and exhausting -- getting the instruments shipped, setting up the demonstrations, daily on our feet, engaged in conversations. You can see in the thumbnail picture here that it was busy -- it was like that all day, every day of the meeting.

Sometime in the distant past, grazing animals on the African Savannah switched their diets from trees and shrubs to grasses. And carbon isotopes tell the tale.

Discussions on the topic of atmospheric research almost inevitably invoke some form of the question: What is the source? Talk to most atmospheric scientists about this question and usually one of the first things they will mention is the inherent difficulty in separating out man-made emissions from Mother Nature's normal, but complex cycles. Combustion engines and gas pipeline leaks release CO2 and methane into the atmosphere, but then again, so does the annual spring thaw in the Northern Hemisphere.
Picarro at EGU 2011 in Vienna: Three New Products, Three Recent Products, Lots of Great Customer InteractionApril 4, 2011 - 10:07am — Alex Salkever
There are two big conferences that we pull out the stops on - the American Geophysical Union annual meeting in San Francisco and the European Geoscience Union annual meeting in Vienna. This is EGU 2011 and we are on the floor (in Booth 49). Like other companies, we like to launch new products around these shows because its the best time to get guaranteed facetime with potential customers who are usually scattered around the globe.
IM-CRDS: Finally, A Better Way to Extract and Analyze Water Isotopes from Plant Leafs, Soils, Tissues - Precise Data in <5 MinsApril 4, 2011 - 9:26am — Alex Salkever
At Picarro, we not only like to make great instruments but we also like to deliver real-world solutions to difficult problems facing scientists. Extracting water samples for isotopic analysis from plant leafs, stems, soils, small organisms and other small samples has been a difficult problem. Legacy technology required massive cryogenic distillation systems that occupy an entire lab bench, require a highly-skilled technician to process a sample, and also required a large sample volume to distill down. Oh, and the process took 90 minutes or more.

We were excited to see that Picarro customer Earth Networks has won an award as one of the 10 Big Idea winners for the Earth2Tech/Gigaom Green:Net conference this April. The award went to Earth Networks in a large part because of their ambitious plan to build the world's largest and first privately funded greenhouse gas measurement network.
Carbon Sequestration with Verification: Monitoring Carbon Capture and Sequestration Projects is Good Science, Good ValueMarch 29, 2011 - 7:29am — Alex Salkever
In Europe and the in North America a variety of big carbon sequestration projects are taking shape. Futuregen, the huge next generation coal-fired power plant in Illinois (pictured here), would involve a massive sequestration effort with injection of CO2 deep into rock formations beneath the surface.

Recognize this? You could take a picture like this in almost any lab around the world. Carefully taped on the front of a tremendously expensive, state of the art piece of equipment, a little rectangle of paper with the name and number of the person to call when the darn thing breaks. You can find these cards everywhere - in research institution, industrial plants, academic labs. Sometimes the card is yellowed with age, or covered with amendments, additional numbers, and notes on how to make the darn thing work.

This is a picture from one of our customers / collaborators, John Stix and fellow intrepid researchers from the Earth and Planetary Sciences Deparment at McGill University in Canada. We believe this is the first time anyone has driven a live, running anallyzer up and down a smoking volcano to capture gas concentration samples.

A fascinating question scientists have long entertained is why do most bats primarily choose to fly at night? And why have they evolved so heavily towards nocturnal activity? The strongest hypothesis about this related to predator avoidance. But no one knew exactly why.

We're in an interesting spot, providing instruments to such a wide variety of folks – we have thought leaders in the greenhouse gas and isotope world who have years of experience using and development their own instruments and measurement methods. On the other end, we have entering undergraduate students who find themselves in front of one of our analyzers – and being able to produce data with it with virtually no training, since the instruments are easy to use and reasonably inexpensive relative to earlier technology… and that’s a good thing, though there are caveats.
