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...
`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...
HITEMA is able to offer a wide range of chiller solutions where one of the main scope is to avoid critical situations during fermentation reaction managing with high competence and experience all the process temperatures during wine production to obtain high quality level of final product.
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.
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...
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...
The method is used for the determination of the mass fraction of total inorganic cations (ammonium potassium, sodium, magnesium, calcium) in all types of feedstuffs, compound feeds, fodders, premixes, fodder additives, and feed raw materials (of plant, animal, and mineral origin) by capillary electrophoresis.
The method is used for the determination of the mass concentration of oxalic, formic, fumaric, succinic, malic, citric, acetic, propionic, lactic, benzoic, sorbic, butyric acids in fodder additives and butyric acid in silage and haylage by capillary electrophoresis.
The method is used for the determination of the mass fraction of ascorbic acid and its salts in food additives and fodder additives (feed additives).The present method does not allow the determination of ascorbic acid in premixes.For the determination of acetic, benzoic, butyric, citric, formic, fumaric, lactic, malic, oxalic, propionic, sorbic, and succinic acids in fodder additives and butyric acid in silage and haylage use the method М 04-74-2012 (Lumex Instruments set, order No 0300001897).
TenCate Geotube technology is used for agriculture applications to reduce the waste in lagoons and utilize the contained nutrients for crops. This dewatering technology reduces the lagoon size by 50%, reduces labor and energy for land application by 50-70%, stores contained nutrients until needed for crops, provides higher quality flush water and reduces the odor and insect problems normally encountered. Over time, these solids dry in the dewatering containers, making the contained nutrients easier to transport...

The method allows determination of herbicides classified as phenoxycarboxylic acids, specifically: 2,4-dichloro-- phenoxybutyric acid (2,4-DB), 2,4-dichlorophenoxypropioni c acid (2,4-DP, Dichlorprop), 2,4-dichloropheno-- xyacetic acid (2,4-D), and phenoxyacetic acid in samples of natural, potable and treated waste water by capillary electrophoresis.
The method is used for the determination of the mass fraction of free choline (synthetic and natural) in feedstuffs by capillary electrophoresis. The method can be applied for all types of feedstuffs, compound feeds, fodders, premixes, fodder additives, and feed raw materials. The present method does not allow the determination of bound choline.
The controlled composting of organic waste with the Toptex protection fabric leaves odour emissions at bay and increases the quality output significantly. Composting is the conversion of organic wastes into high quality humus. Through systematic controls these materials can be returned to the earth, completing the cycles of nature and improving the soil to which it is applied.
There is a growing demand for more efficient, effective and durable solutions in the Agro industry. For TenCate this is a constant motivation to develop – often in close cooperation with our customers – the best solutions.
