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...
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...
Recycling carbamate solution back to urea-reactors (Stamicarbon- and Snamprogetti-Processing Methods) will be done world-wide more or less exclusively with Körting high-pressure liquid jet ejectors (H.P.-ejectors). Multi-stage steam jet vacuum systems specifically designed to meet the requirements of urea evaporation stages have been in use for many decades now with great success. New developed boosters and vacuum condensers are available to provide an extremely economical and trouble-free operation.
Monitor and report the flow in your irrigation system. As a manager of an irrigation district, farmer, or city operations manager, a KISTERS solution provides an effective tool for easily managing, analyzing and reporting on irrigation activities. Even use it to calculate pump efficiencies, leak detection, water balances and monitor water supply contracts!
Use KISTERS solutions for gathering of meteorological, soil, and other timely crop data from the field. Easily remove the difficulties in comparing statistics and validating information collected for the monitoring and measuring of agricultural production.
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...
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...
The dust generated at various times during the production and processing of materials in factories is often unpleasant and pollutes the environment. Such situations arise, for example, in steel production, when disposing of slag, in cement production or in the lumber industry. EmiControls products have the versatility and flexibility to be adapted to a wide and diverse range of situations, enabling measures to be taken that combat these sources of dust effectively and drastically reduce their levels inside and...

The mercerisation of cotton materials yields large quantities of weak caustic soda. Recovery of mercerising lye by means of our Körting evaporation technology developed specially for this process results in an immense saving of costs and a minimised impact on the environment. When combined with a specially co-ordinated lye cleaning system the result is a nearly 100% recovery of lye.
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.
Enteric disease costs the global livestock and aquaculture industry more than nine billion dollars annually. Amlan International, Oil-Dri’s animal health business, offers natural intestinal health products to manage the health and productivity of livestock around the world.
