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.
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
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.
The Aquaculture industry is one of the fastest growing segments in the agricultural industry accounting for over 1.13 billion dollars in the USA alone. However, this industry is suffering with several water quality challenges requiring sustainable aquaculture water treatment solutions to enhance fish health, and population yield while meeting environmental discharge regulations. The challenges facing aquaculture companies include emerging growth rates of specific bacteria and viruses, water usage, and environmental...
Our UV water disinfection technology is used in fish farms, mussel farms, aquariums and hatcheries. The benefits of UV disinfection has led to the production of healthier and larger fish, improved water quality, possible increases in stock density and vastly reduces the risk of disease. UV light is a chemical free treatment that cannot be overdosed, ensuring the physical characteristics of the water, such as PH levels and temperature, remain unchanged whilst avoiding the introduction of harmful toxins, such as...
The agriculture industry is a water intensive industry that needs a constant contaminant free water supply to ensure high harvest yields and healthy farm livestock. Agriculture in the U.S. is dominated by large, specialized crop and animal farms. These industrial farms focus on short-term productivity, often at the cost of creating environmental and public health problems. This focus on short term productivity, requires agriculture water treatment solutions and specific soil additives that are sustainable and...
Salt Out™ reduces or eliminates salinity stress in plant growth by sequestering sodium and chloride ions from penetrating plant root tissues. These conditions usually occur due to the buildup of salts as a result of fertilizer applications, irrigating with reclaimed, well or pond water, as well as salts deposited by ocean mist.
Salt Out™ coats the plant roots disallowing the update of the salts thereby enhancing nutrient uptake resulting in rapid improvement and stabilization of turf color.
Salt Out™ also...
Alfalfa is a crop of the legume family and its scientific name is Medicago sativa. Alfalfa is a perennial plant of erect growth and is one of the most extended forage crops within temperate climate countries.
The maize is a crop of the gamine family coming from Centro America and with thousand of years old. The approximate world production is of 790 millions of tons of grain in 158 millions of hectares. The main producers are United States, China, Brazil, having nearly the 62% of the total world production.
Ammonia (NH3) is formed from the breakdown of urea in slurry and manure, and hence this is the main source of NH3 emission in the UK. High levels of NH3 emissions can cause a large amount of environmental damage to vegetation. As well as the outward environmental impact, high NH3 concentrations in and around livestock enclosures have a detrimental effect on the health and well-being of the animals.
