A gas concentration image (i.e., concentration vs. position data) in a cross section through a gas plume is obtained. Such measurements can be obtained by moving a 1D array of gas sample inlets through the gas plume. By combining a gas concentration image with ambient flow information through the surface of the gas concentration image, the leak rate (i.e., gas flux) from the leak source can be estimated. Multiple gas analysis instruments can be employed in connection with sweeping a 1-D array of measurement ports through the gas plume in order to reduce analysis time.


This work provides event selection in the context of gas leak pinpointing using mobile gas concentration and atmospheric measurements. The main idea of the present approach is to use a moving minimum to estimate background gas concentration, as opposed to the conventional use of a moving average for this background estimation.

Optical spectrometer apparatus, systems, and methods for analysis of carbon-14 including a resonant optical cavity configured to accept a sample gas including carbon-14, an optical source configured to deliver optical radiation to the resonant optical cavity, an optical detector configured to detect optical radiation emitted from the resonant cavity and to provide a detector signal; and a processor configured to compute a carbon-14 concentration from the detector signal, wherein computing the carbon-14 concentration from the detector signal includes fitting a spectroscopic model to a measured spectrogram, wherein the spectroscopic model accounts for contributions from one or more interfering species that spectroscopically interfere with carbon-14.


Research and Markets (http://www.researchandmarkets.com/research/8x5q2g/food_traceability) have announced the addition of the "Food Traceability Market by Technology, End User, Application & Region - Global Trend & Forecast to 2019" report to their offering. The food traceability market is projected to grow at a CAGR of about 9% from 2014 to reach $14,304.9 million by 2019 Food traceability facilitates tracing food products or ingredients through all stages of production, processing, and distribution. It involves the use of tracing systems and processes that match the features of incoming raw materials to outgoing product specifications for the purpose of improving business performance. In the food industry, food traceability is used for fresh food produce, meat products, dairy products, beverages, seafood products, and others. The growing consumer concern for food safety and increasing incidents of food adulteration are some of the driving factors for the food traceability market. However, the high cost incurred by the food traceability equipment, and the privacy issue involved are restraining the growth of the market. The continuous development in emerging markets such as Brazil, India, and China is paving new opportunities for the food traceability market. The food traceability market is segmented on the basis of technologies, end users, applications, and regions. The application industries for food traceability include meat products, fresh food produce, dairy products, beverages, seafood products, and others such as grains, oilseed, and coffee. The end user of food traceability is segmented into food manufacturers, warehouse/pack farm, food retailers, defense & security departments, and others such as government departments.
