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.

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...
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...
A group of 30 compounds was selected, representing pesticides, acaricides, insecticides, and fungicides. These samples were analyzed using Supel™ QuE QuEChERS and an Ascentis® Express RP-Amide HPLC Column.
Globalization puts ever-increasing demands on the food and agriculture industry. Highly sensitive analytical instrumentation is key for reliable monitoring of food products along the food chain starting from agricultural production over food processing and packaging to distribution and consumption. Analytik Jena analytical solutions help you meet industry standards during both development of new products or quality control assessment.
`A technique of growing plants in nutrient solution”. Hydroponics literally means water-working or water-activation. It is a cultivation technique for growing plants in highly oxygenated, nutrient enriched water, rather than soil. The nutrient solution and its management are the cornerstone for a successful hydroponics system. The function of a hydroponics nutrient solution is to supply the plant roots with water, oxygen and essential mineral elements in soluble form. In soil, biological decomposition breaks down...
Cambridge based Delta-T Devices specialises in instruments for environmental science, in particular: agronomy, plant physiology, eco-physiology, data logging, meteorology, soil moisture, solar energy studies and environmental monitoring.
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...
Accuracy and ease of use make SM300 Soil Moisture Sensors well suited to irrigation applications. Readings can be used to optimise irrigation scheduling, or the SM300 can be installed as part of an automatic irrigation system. The sensor`s compact size allows it to be installed in plant pots or grow bags.
Delta-T Devices supplies high quality, research grade equipment to help growers monitor and control irrigation using proven technology:
improve water use efficiency
reduce fertiliser application rates
enhance crop development
Farmers and researchers in the agricultural industry have used AMS sampling equipment for over 50 years. The AMS Step Probe, Soil Recovery Probes, and a variety of one and two-piece augers are used in the agricultural sampling market to obtaining disturbed samples at or near the surface and for boring to depths where more precise samples can be obtained. AMS now offers a variety of nematode sampling equipment, ATV-mounted PowerProbe rigs, and one and two-piece open-faced augers.
Television and radio news reports and regional forecasts have their role and are important sources of general information for managing an agricultural operation. But these reports probably don’t represent the conditions at your specific site – what about your local weather conditions?
Abattoir & Slaughterhouse waste is a potential incubator of bacterial, viral, prion and parasitic pathogens, capable of infecting both animals and humans. A quick, cost effective and safe disposal method is essential in order to reduce the risk of disease following animal slaughter.
Agro-meteorological application (AgMet) are becoming more and more important. With a rising world population, agricultural production has to become more efficient. Water is precious and scarce, pesticides are expensive and harmful to the environment if they get into the soil.
Feeding sprouts can replace 100% – 60% of your current hard feed diet. Horses that need a high starch feed will require a supply of starch from conventional feed such as steamed flake barley. The high moisture content of sprouts benefits digestion and recovery after work. For digestive health it is recommend that a horse consumes a min. of 1.5% of its body weight as dry matter. This needs to be considered when calculating the required roughage to balance your horse’s diet when feeding spouts.
