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...

`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...

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.

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...

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.

Nicolon Ground Cover Fabrics control weeds found in land maintained by professional growers and landscapers. These highly useful fabrics feature woven polypropylene that allows water and nutrients to pass through while preventing roots from implanting into the soil. Available in widths from 3 to 15 feet (0.90 x 4.5m), Nicolon ground cover fabrics can also be utilized in soil separation and barrier fencing applications.

The Toptex fabric is a high grade membrane to protect straw, sugar beet and potato harvests from frost and rain, thereby reducing the amount of clinging clay on beets or potatoes and efficiently leading to less cleaning water needed in the process. On top of this, dried harvests offer a higher yield for the farmer and better quality for the consumer.

The method enables fast quantitative determination in feeds, mixed fodders, and raw materials of the following amino acids: arginine, lysine, tyro sine, phenylalanine, histidine, leucine and iso -leucine (total), methionine, valine, proline, alanine, glycine, cystine, tryptophan, aspartic and glutamic acids.

Since during the sample decomposition asparagine and glutamine are hydrolyzed to aspartic and glutamic acids, respectively, the content of these two acids represents the total content of both the...
