Gas Chromatography

Still hot: gas chromatography has been around for some time but has constantly been improved. Today’s instruments are more rapid and sensitive and are able to work with a variety of detectors. Coupled with mass spectrometers (GC-MS), gas chromatographs can not only separate the substances in mixtures but also easily identify and quantify them. For several industry applications combination systems are available that, for example, also encompass TG and LC.

  • Staying power

    Geoscientists, biologists and chemists at the University of Tübingen are working in collaboration with IFAM (Fraunhofer Institute for Manufacturing Technology and Advanced Materials in Bremen, Germany) to uncover the workings of insect surface adhesion. The goal of this project is the synthesis of an adhesive based on insect secretions. more

  • Pollutants in ocean-floor sediment

    What kinds of contaminants are enriched in sediment – and are these then absorbed by the organisms that live there? What role do microplastics play? To answer these questions, Professor Gesine Witt’s team is using pollutant samplers made from silicone-coated glass fibre to investigate the sea floor. And not just as research for research’s sake but because the protection of our environment is a top priority. more

  • A Complex Mixture

    Once only of academic interest, the combination of liquid chromatographic separation with subsequent separation in the gas-phase is proving to be suitable for routine use. In routine laboratory work, the method continues to present a major challenge, above all with regard to precision, repeatability and robustness. A sophisticated coupling of methods can offer decisive advantages, through a greater degree of automation. more
