Applications

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...

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...

Control Composting Odors, Naturally: Municipal sludge is often composted in indoor facilities or composting sheds. These areas create significant odor control challenges. Ecosorb products, either evaporated or atomized in concentrate form with nozzles or humidifying fans, control industrial odors even in very large composting facilities.

Three reasons why ozone in aquaculture improves water quality and increase aquaculture productivity. As recirculating aquaculture systems (RAS) operate by reusing the fish tank water it is essential to control the water quality. Many studies show that treating RAS systems with ozone increases productivity as fish health and survival is increased.

Mycotoxins are a diverse group comprised of hundreds of secondary metabolic products of various fungal species. Several show marked toxicity in humans. Contamination of the food supply with mycotoxins is increasingly prevalent, and can occur during growth, harvest, transportation, processing or storage. Techniques to reduce mycotoxin concentration after contamination are expensive, unreliable and sometimes reversible. Therefore, the removal of contaminated products from the food chain is a primary means of...

The US FDA and international regulatory agencies have set contamination levels for aflatoxins in animal feedstuffs. Since Aspergillus may infect commodities pre-harvest, during storage or during processing, monitoring for aflatoxins in associated agricultural commodities at all stages of production is requisite. Field screening methods exist that are adequate to estimate contamination levels for aflatoxins. When additional confirmation or quantification is desired, chromatographic laboratory analysis is often...

`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...

Maintain healthier ponds, increase stocking densities, and generate higher yield with optimum oxygen transfer. Maintaining the proper level of oxygen dispersion in your systems is critical to the success of your operation – and the life of your fish. Poor dissolved oxygen levels, fluctuating water temperatures, and stratification all can negatively affect fish health and pond production.

Introduction

The method is intended for determination of hesperidin and naringin using capillary electrophoresis technique in order to reveal adulteration of juices. These components are tested in citrus juices, concentrated juices, nectars, juice-containing beverages, and fruit sauces that are produced primarily from oranges, grapefruits, tangerines, lemons, and limes.

Introduction

Fungicide Carbendazim (Mercazole, Carbendazole) is widely used in agriculture to exterminate black mold (spot) on orange trees and treat fungus diseases of other fruit-bearing plants. According to the data of the World Health Organization, Carbendazim is toxic for liver, impacts reproductive system, and is considered to be a potentially cancerogenic compound. In most of the developed countries, the residual content of this fungicide is subject to national and international...
