    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.

    Mercury monitoring for isotopic abundance by the ICP-MS

    Studies of real-world ecosystems are very complex. Mercury species inter-conversion as well as mercury deposition and evasion are constantly occurring. One technique to help sort out the processes is to trace reactions using natural Hg isotopes. Either by enriching a system with a particular isotope or determination of isotopic ratios as a technique of source identification, isotopes are a powerful tool for investigation. The Tekran 2600 Total Mercury and Tekran 2700 Methyl Mercury systems are designed to couple to an ICP-MS for mercury quantification by CVAFS and isotopic abundance by the ICP-MS.

    Measurement solution for FTIR Vs. GC in gas analysis

    Comparison of Technologies

    A gas chromatograph (GC) has traditionally been the technology of choice for laboratory analysis of gas samples. GCs have been used for over 50 years in the qualification and quantification of complex mixtures of gases. The techniques and methodology required to run GCs are often a pre-requisite for any laboratory technician. Recent developments in Fourier Transform Infra-Red (FTIR) gas analysis has enabled this technology to start to replace GCs in the lab.

    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.

  • 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.
