  • Improved Reproducibility and Reduced Sample Preparation Time for the HPLC Analysis of Aflatoxins in Raw Peanut Paste

    The US FDA and international regulatory agencies have set contamination levels for aflatoxins in animal feedstuffs. Since Aspergillus may infect commodities pre-harvest, during storage or during processing, monitoring for aflatoxins in associated agricultural commodities at all stages of production is requisite. Field screening methods exist that are adequate to estimate contamination levels for aflatoxins. When additional confirmation or quantification is desired, chromatographic laboratory analysis is often necessary. Preparation of matrix samples prior to chromatographic analysis typically requires extraction and purification. Commonly, immunoaffinity columns (IAC), which employ a multi-step bind and elute mechanism to concentrate and purify aflatoxins, are used to purify matrix samples for subsequent analysis. Solid phase extraction (SPE), an alternate method which may use interference removal, can also be employed.

    EDXRF spectrometers for pharmaceutical industry

    The pharmaceutical industry is one of the most regulated industries. Contaminants in drug products are examined throughout the manufacturing process, since their presence affects drug stability, behaviour and toxicity. Therefore, regulatory bodies such as the European Medicines Agency (EMEA) and the American Food and Drug Administration (FDA) strictly enforce continuous and ongoing analysis of organic or inorganic impurities from raw materials, excipients and Active Pharmaceutical Ingredients (API) through intermediates of drug products and packaging.
