  • Environmental technology for fertilizer production industry

    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.

  • Rapid Determination of Pesticides in Spinach

    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 SPE tube uses spherical materials for both the carbon and NH2 layers, providing fast, more consistent flows compared to tubes containing granular material. This allows gravity elution (instead of vacuum elution) to be applied to Supel Sphere tubes, resulting in more contact time between extracts and sorbents.

  • Improved Recovery of the Fungicide Carbendazim

    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 cleanup, suitable for various orange juice matrices. The choice of PSA/C18 sorbents reduced interferences, resulting in greater recoveries and less ion-suppression. Because the QuEChERS method is fast, it only adds a few minutes to the sample preparation procedure. Sample processing using QuEChERS with PSA/C18 allows analysts to accurately process various matrices in a single workflow, with very little additional sample preparation time.

  • Improved Resolution of Mycotoxins from Cereal

    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 eliminating human exposure. The sensitive and accurate detection of very low levels of these compounds is critical to efforts to identify contaminated products. LC-MS/MS is a popular analytical technique for this purpose. This application explores using Ascentis® Express RP-Amide and Ascentis Express F5 HPLC columns to perform this analysis.
