A Wonderful Video Introduction to Stable Isotope Analysis for Food Safety

Concerns about food safety and food origins are increasing around the world as our understanding of the potential health risks of adulterated food grows and consumers become aware of the risks of fraudulent food products that have been diluted with lower quality substitutes. Picarro's technology is at the forefront of the fight against food adulteration. Our isotopic analyzers allow scientists and regulators to analyze food ingredients to determine whether the food is genuine and came from where its label says it came from.

A trip on the Sacramento-San Joaquin River Delta with USGS

After introducing our local collaborator, Carol Kendall from the U.S. Geological Survey (USGS) in Menlo Park, to the concept of the CWS, she cooked up a great plan for us to join Brian Bergamaschi and Bryan Downing from the USGS California Water Science Center in Sacramento on one of their upcoming delta mapping trips.

Using stable isotopes of water for water use efficiency in agriculture

I just returned from a week-long trip to Dubai where I was fortunate to participate in and help lead an International Atomic Energy Agency Regional Training Course on “Separating evapotranspiration (ET) into evaporation (E) and transpiration (T) using isotopic and conventional techniques”. The five day technical course gathered about 15 scientists from across the Middle East region to learn about the importance of understand water use efficiency in agriculture, and in particular how to use stable isotopes of water to partition water loss from crops into “good” water loss (transpiration) and “bad” water loss (evaporation).

Are you concerned with the Adulteration of Honey?

Are you aware that more and more honey suppliers and distributors are using stable isotopes to certify their products are free from adulteration? In addition, Customs and Border Protection agencies around the world regularly test for adulteration in imported honey products. Your customers will soon demand this information from you, or they will be forced to choose other suppliers.

Crowd-sourced isotope study of Superstorm Sandy

By Guest Bloggers Stephen Good and Gabe Bowen: Well, we’re approaching the two-year anniversary of Hurricane Sandy, and we figured it would be a good time to reminisce about that intensive sample storm that swirled through our Utah lab after the floodwaters of Sandy subsided in New Jersey…

Goldschmidt 2014 and ASITA keep us busy for the month of June!

In early June we made the short trip from Picarro’s Headquarters in Silicon Valley to Sacramento and Davis for Goldschmidt 2014 and ASITA. Although pretty different conferences, we had a great time at both and had some excellent conversations with globally-recognized isotope geochemists, newcomers to the field, avid Picarro users and those just getting into the game.

Highlights from EGU 2014

.all-attached-images { display: none; } We had a great time at EGU 2014 in Vienna, Austria! We enjoyed meeting everyone and learning more about the great research taking place across water, air and soil applications. We were excited to see the interest in our demos and look forward to sharing our analyzers in action at future events. Our Tech Talk turnout was amazing and we hope you enjoyed the poster sessions featuring Picarro instruments.

Valerie Morris, Bruce Vaughn and the INSTAAR Stable Isotope Lab Team

It's time for a celebration at the Institute of Arctic and Alpine Research (INSTAAR) Stable Isotope Lab (SIL). Valerie Morris, Bruce Vaughn and the SIL team have reached the top of the WAIS Divide Ice Core! Using a custom-built continuous flow melt system coupled to a Picarro L2130-i, the SIL team has completed stable isotope analysis of the West Antarctic Ice Sheet Divide 06 A core. This is the first top-to-bottom continuous ultra-high resolution isotopic record from a polar ice core.

USGS/CUAHSI Virtual Workshop on Laser Spectroscopy

The Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI), in partnership with USGS, recently hosted a Virtual Workshop on Laser Specs for Field Hydrology and Biogeochemistry: Lessons Learned and Future Prospects. I was invited to present on Picarro and Cavity Ring Down Spectroscopy as applied to hydrology and biogeosciences, and you can watch the webinar here...

Highlights from the 2013 ASA, CSSA & SSSA Meetings in Tampa FL

November kicked off with the Soil, Crop and Agriculture Science Societies annual meetings, held this year in Tampa, FL, November 3-6. For those who were not able to attend, the focus of the meetings was Water, Food, Energy and Innovation for a Sustainable World. Six topical themes were covered: Sensing Innovation, Climate Change, the Food-Water-Soil Nexus, Sustainable Agricultural Systems, Improved Nutrient Management, and Energy, Soils, and Crops.

Eosense brings membrane technology to simplify soil gas efflux measurements

Did you know that soils produce 10 times more CO2 than all fossil fuel combustion? Surprisingly, it is true. Soil respiration produced 119.6 GigaTons of carbon per year during the 1990s, which far out paces the 6.4 GigaTons of carbon produced annually by the burning of fossil fuels in the same period (IPCC, 4th assessment, WG I, 2007, Figure 7.3).

A trip to Paris is never a bad thing...

A trip to Paris is never a bad thing, especially when the excuse is a gathering of about 50 of the top atmospheric scientists from around the world who are using water vapor isotopes. Last week, scientists from Laboratoire des Sciences du Climat et l'Environnement (LSCE) hosted an intimate workshop on “Advances In Observations, Models And Measurement Techniques Of Atmospheric Water Vapor Isotopes” at the Centre National de la Recherche Scientifique (CNRS) in Gif-sur-Yvette.
