    AutoChem - Process Analytical Technology (PAT)/Quality by Design (QbD)

    Process Analytical Technology (PAT) has been implemented for years, particularly by the chemical industry for the control of chemical processes. More recently, PAT has become a cornerstone of the US Food and Drug Administration’s (US FDA) Quality by Design (QbD) initiative for both the design and control of quality processes. For this reason, the pharmaceutical industry is also active in utilizing PAT tools. PAT tools can be implemented in both the lab and the plant, with laboratory PAT focused more on the design of a quality process and with plant PAT focused on the monitoring and control of the process.

  • Reduced Fat Interference with Analysis of Pesticides in Avocados

    QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) is a very popular method for the extraction and cleanup of fruit and vegetable samples for pesticide residue analysis.2-4 The extraction step uses acetonitrile and a salting out effect (with MgSO4). Cleanup is then accomplished using dispersive SPE (dSPE) followed by a centrifuge step prior to analysis. This application shows the clean-up and analysis using Supel™ QuE Z-Sep+ QuEChERS and an SLB®-5ms GC column.

  • Increased Pigment Removal with Analysis of Pesticides in Oranges

    An application was developed to demonstrate increased pigment removal for the analysis of pesticides, using Supel™ QuE Z-Sep/C18 QuEChERS and an Ascentis® Express C18 HPLC Column. The improved cleanup can decrease column and instrument fouling, leading to extended LC column lifetime and reduced instrument downtime.

  • Analysis of Methylimidazoles in Caramel Colored Carbonated Beverages

    Caramel colorings are used as additives in a broad range of food and beverage products to impart a desired color, but have no nutritional or preservative function. Recently, the potential hazard to humans of ammonia- and ammonia-sulfite-process caramel colorings was raised, because they contain the by-product 4-methylimidazole, which is a potential carcinogen.1 The methylimidazole compounds are difficult to analyze due to their polar nature and low molecular weight. Traditional reversed phase techniques are unsuccessful in retaining these small polar compounds. Therefore, most HPLC methods utilize ion-exchange resins for analysis. Another common method involves GC analysis after the analytes first undergo a derivatization step. The purpose of the work shown in this article was to develop a simple and fast analytical method to determine the levels of 2-methylimidazole and 4-methylimidazole in caramel colored carbonated beverages.

  • Pesticide and toxin screening for the food industry

    The number of pesticides and other potentially dangerous toxins is increasing constantly, posing special analytical challenges. It is crucial to screen food for the presence of toxins accurately and reliably, and to ensure the safety and quality of nutrition. To do so, we have to have the knowledge about how to deal with several hundreds of different poisonous matters. Bruker delivers solutions that meet the requirements for the identification and quantification of toxicants during the screening of each sample. Bruker’s high-performance TOF-MS is ideally suited for all screening tasks. And Bruker’s SCION series sets a new industry standard for GC-MS. Their easy usability, sensitivisty, robustness and performance make SCION solutions a major technology in food safety.

  • Analysis of Pesticides in Beef Kidney

    The suitability of the new cleanup sorbent, Supel QuE Z-Sep+, has been successfully demonstrated for cleanup of beef kidney matrix. It was found to effectively reduce background without significantly reducing recovery of lipophilic pesticides such as organochlorines and some pyrethroids. GC-MS full-scan data indicated Z-Sep+ was found to provide better cleanup in the form of reduced background than PSA/C18, and less interference in the GC-MS/SIM analysis of the target pesticides themselves.

  • A New GC-MS Method for Mycotoxin Analysis Using 13C-marked Mycotoxin Derivatives

    Andreas Breidbach [1] and Wolfgang Brodacz [2,3,4] developed a new GC-MS method using fully 13C isotopelabelled analogues of T-2 toxin and HT-2 toxin that allows for the detection of these toxins at concentrations as low as 2–5 ppb.
