    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.

    Analysis of Herbicides in Drinking Water

    Herbicides are used throughout the world to combat the growth of unwanted plant life. These polar compounds are hydrophilic, so they may find their way into drinking water sources. While gas chromatography has historically been the preferred technique for analysis of herbicides in water samples, the use of LC-MS/MS for this application is gaining acceptance. This is due to the power of MS/MS to provide detailed identification of multiple analytes, but also in part due to the variety of HPLC stationary phases that are available. In particular, several HPLC phases are available that provide great retention and peak shapes for polar analytes, such as herbicides, even under mostly aqueous mobile phase conditions. The combination of these factors may possibly eliminate need for time-consuming sample preparation.

    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.

    Measurement of C1-C5 with carbon dioxide for oil & gas exploration.

    The PetroAlert Model 8900 combines the selectivity of gas chromatography with the sensitivity, broad dynamic range, and hydrocarbon selectivity of a flame ionization detector (FID) providing fast analysis of C1-C5 hydrocarbons and Carbon Dioxide required in Mud Logging for Oil & Gas exploration. The PetroAlert Model 8900 uses a dual column configuration with timed backflush to vent which is used to strip off moisture and C6+ hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed sample volume is carried to the pre-cut column. Backflush of the pre-cut column is timed from sample injection so that only C1-C5 hydrocarbons are eluted from the pre-cut column to the analytical column. C6+ hydrocarbons on the pre-cut column are then vented.

    Measurement of ethylene oxide for monitoring workplace exposure limits

    The Series 8900 Ethylene Oxide Analyzer combines the selectivity of gas chromatography with the sensitivity of a Photoionization Detector (PID) providing interference free response to Ethylene Oxide (EtO) at levels below 0.05 ppm. This analytical method is referenced in OSHA`s `Occupational Exposure to Ethylene Oxide: Final Standard` 29 CFR Part 1910. The system documents exposure levels including: time-weighted averages (TWA), short-term exposure limits (STEL) and instantaneous alarms. Areas that are typically monitored include; EtO Sources - gas storage areas, sterilizer doors, aeration doors, and the General Work Area - decontamination, packaging and preparation and sterile product storage areas.

    Machine condition monitoring for labs & services

    Overview

    Machine condition monitoring using oil analysis is widely practiced by virtually every segment of modern industry that maintains large, expensive, oil-lubricated machines. In many cases, especially in smaller plants or enterprises, samples are sent to commercial oil analysis laboratories that can help monitor machinery health.

  • 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.
