If you are attending the 2018 EGU General Assembly from April 9 to 13 in Vienna, Austria, we hope you’ll stop by Picarro booth 28 and spend some time with Picarro team members. We welcome an opportunity to meet you and learn more about your ongoing research programs. And we’ll have Picarro isotope and gas concentration analyzers on display that may be of interest to you, including...

该系列文章由三部分组成，本文为第二篇，探讨了 Picarro 分析仪、系统和配件如何确保对具有挑战性的海水和高盐水样品实现准确测量。第一篇文章海水的水稳定同位素测量介绍了实验室间的研究结果，该研究旨在评估与同位素比质谱 (IRMS) 测量结果的一致性和值相比，通过光腔衰荡光谱 (CRDS) 所得测量结果的质量。本篇文章报道了对 CRDS 用于高盐水分析的评估。

We developed our water stable isotope analyzers, system peripherals, and accessories to give research scientists a less-expensive, easier-to-use solution for precise, accurate isotopic measurements. They’ve been used successfully in freshwater research for over a decade. More recently, scientists have tested our analyzers and systems, and we’ve continued to develop accessories to ensure precise, accurate measurements of more demanding seawater and high-saline water samples. This is the first of a three-part series that examines...

　　在皮卡罗 (Picarro) 公司，我们经常会撰写关于我们产品和应用的文章，但更愿意阅读客户是如何在他们的研究项目中运用我们的产品和应用的内容。科尔·布拉赫曼 (Cole Brachmann) 、吉耶尔莫 赫尔南德斯·拉米雷斯 (Guillermo Hernandez Ramirez) 和大卫·希克 (David Hik) 与埃德蒙顿阿尔伯塔大学生物科学系和可再生资源系花时间撰写了一篇关于他们所实施的夏季土壤通量研究的短文。感谢这三位人士与我们分享经验。

We've just introduced the Picarro G2207-i gas concentration and isotope analyzer for atmospheric applications including oxygen monitoring to identify the biogeochemical process involved in the carbon cycle. The analyzer combines high precision and low drift O 2 concentration measurement with δ 18 O analysis in ambient air.

We've just introduced the new Picarro PI2114 hydrogen peroxide gas concentration analyzer for GMP pharmaceutical manufacturing. You can learn more about it and download a data sheet at www.picarro.com/pharma . Here's a short description about the applications it addresses and the benefits and advantages of using it.

The production, sale, and distribution of coconut water is a multibillion-dollar global industry. Given the increase in preference and consumption of pure ‘organic' coconut water, producers are challenged to ensure product purity and maintain customer confidence. This demands an absolute method for producers to distinguish between ‘pure' coconut water, without added sugar, and ‘adulterated' water, with added sugar. The Picarro Combustion Module Cavity Ring-Down Spectroscopy (CM-CRDS) System is a low-cost, easy-to-use, accurate, and precise solution to identify the addition of C4 sugars (adulteration), based on the carbon isotopic (δ 13 C) composition of coconut water.

We introduced the Picarro GasScouter™ mobile gas concentration analyzer to make it easier for scientists to perform high-precision measurements of carbon dioxide (CO 2 ) and methane (CH 4 ) in the world’s most challenging, remote environments. And scientists at the University of Copenhagen are seizing the opportunity to use the new-generation, light-weight, portable, battery-powered cavity ring-down spectroscopy (CRDS) gas concentration analyzer at both ends of the Earth.

Picarro's partnership with PG&E continues to make headlines. Using Picarro technology, PG&E is able to perform a precision survey and maintenance operation on 5200 gas lines in Yolo county that would normally take four months in only two weeks.

Author: Nick Nickerson, Eosense Gas analyzers have become increasingly more precise over the past 10 years with the adoption of laser-based sources and ultra-long path length optical cells. However, usually this has been at the cost of power consumption, making them difficult to easily deploy in the field, especially off-grid.

If you saw one rolling through the neighborhood, you might mistake it for a Google maps car, but for more than a year and a half, PG&E has been cruising for gas leaks, using Ford Explorers that are actually super-sensitive, gas detection vehicles. (KGO-TV)

The hydrologic and carbon cycles in the Arctic are currently changing in conjunction with climatic transitions. This includes changes in sea ice extent and thickness, Arctic Ocean pH, and patterns of primary productivity and food web dynamics. Additionally, sea ice related changes in evaporation processes are influencing winter and summer precipitation regimes and broader scale climatic patterns. For example, Arctic vortex shifts allow more Arctic air to reach lower latitudes, which can result in more frequent extreme weather events in the northeast United States.

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.

This story starts more than 20 years ago when Professor Jeffrey Richey’s research group started to consider the importance of the tropics, and particularly, the Amazon basin, to the global carbon cycle.

Across the globe ammonia emissions are on the rise. Emissions inventories, and limited networks of ambient air measurements, suggest the rise is predominantly due to intensive farming practices and the increased use of nitrogen-based fertilizers.
