    Improved Recovery of the Fungicide Carbendazim

    Fungicide carbendazim can some times be used to combat mold on citrus fruits including oranges. Recently, low residue levels of the fungicide were reported to be present in the bulk orange juice import shipments to the USA. Because this compound can persist through processing steps and may be found in the final consumer product, many government agencies have established maximum residue limits (MRLs) to ensure the safety of their population. Presented here is a single method, involving fast and effective QuEChERS...

    Analysis of Herbicides in Drinking Water

    Herbicides are used throughout the world to combat the growth of unwanted plant life. These polar compounds are hydrophilic, so they may find their way into drinking water sources. While gas chromatography has historically been the preferred technique for analysis of herbicides in water samples, the use of LC-MS/MS for this application is gaining acceptance. This is due to the power of MS/MS to provide detailed identification of multiple analytes, but also in part due to the variety of HPLC stationary phases...

    Rapid Determination of Pesticides in Spinach

    Highly pigmented foods, such as spinach, require cleanup prior to analysis for pesticide residues. A dual-layer SPE tube containing graphitized carbon and aminopropyl on silica (NH2) is often used because; Carbon removes pigments and sterols and NH2 removes fatty acids, polar pigments, organic acids, and sugars. Removing these matrix materials reduces interferences that can lead to ion suppression in LC-MS, inlet contamination in GC-MS, and column contamination for both techniques. Our Supel Sphere Carbon/NH2...

    Gas analyzers and monitoring systems for Greenhouse gases from ruminants

    Ruminant livestock generate a significant proportion of anthropogenic GHG emissions, and thereby contribute to Climate Change. Ruminants such as cattle. sheep, goats and buffalo produce meat and milk through enteric fermentation – a digestive process in which microbes decompose and ferment food in the digestive tract or rumen. This process produces methane which is emitted via belching. The amount of methane produced is directly related to the type of food consumed and the level of intake, in addition to...
