  • Analysis of Pesticides in Lemon Oil Extract Using Deconvolution Software

    The analysis of food for trace levels of pesticides is commonly performed to meet regulatory requirements and ensure product safety. In some instances, a natural product such as lemon oil is used as a flavor enhancer, and the level of pesticides in the enhancer must be ascertained before it can be added to the foodstuff. The analysis of pesticides in natural products can be fairly challenging, ...


  • Target GC-MS Analysis using Accelerated Column Heating and Interactive Deconvolution Software

    In diverse fields ranging from environmental samples to complex fl avor preparations, high performance, high resolution capillary gas chromatography/mass spectrometry, GC-MS, has become the preferred technique for identifying and quantifying target compounds at trace levels. Many of these samples are characterized by very complex matrices, which provide a substantial challenge for contemporary ...


  • Degradation of carbendazim by UV/H 2O 2 investigated by kinetic modelling

    Abstract The transformation of the fungicide carbendazim (methyl-2 benzimidazole carbamate) induced by hydroxyl radical generated by the UV photolysis of H 2O 2 has been studied in dilute aqueous solution. The efficient reaction of hydroxyl radicals with carbendazim led to the rapid degradation of carbendazim. The study of reaction kinetics yielded a second order rate constant of 2.2±0.3 10 9 M ...

  • ACQUITY Arc System: Transferring Validated HPLC Methods within USP Guidelines

    The thought of transferring established high performance liquid chromatography (HPLC) methods onto a another vendor’s LC, or a new platform like UHPLC/UPLC, may cause a bit of anxiety for those that may be unaware of how easy it can be. The reason that the topic of analytical method transfer induces so much angst is that for the transfer of an LC method to succeed, the method has to work as ...
