  • New Separation Science Slam exceeds all expectations

    On June 18, 2019, the 48th HPLC Conference (University of Milano-Bicocca, Milan, Italy) played host to the debut of the Separation Science Slam, sponsored by KNAUER, Merck and The Analytical Scientist. Six scientists under the age of 35 were given the opportunity to present their scientific work in more

  • ‘Chemputer’ promises app-controlled revolution for drug production

    A radical new method of producing drug molecules, which uses downloadable blueprints to easily and reliably synthesise organic chemicals via a programmable ‘chemputer’, could be set to democratise the pharmaceutical industry, scientists say. In a new paper published online in the journal Science, re more

  • Crystals that clean natural gas

    Removing the troublesome impurities of hydrogen sulfide (H2S) and carbon dioxide (CO2) from natural gas could become simpler and more effective using a metal-organic framework (MOF) developed at KAUST. Upgrading natural gas in this way could help Saudi Arabia to make greater and cleaner use of its a more

  • Trend barometer: taking the underground to the airport

    Yes – you can talk about an ‚underground system’ in terms of analysis. Many samples are forwarded in parallel – including unstyled raw extracts in any condition. The connection to the airport is assured and today molecules can fly in a myriad of different ways. more

  • Workflow

    According to the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), it is necessary to test analytical methods for their linearity as part of a method validation study. The typical process for this is to prepare standards for five different calibration levels, and to make triplicate injections of each of these standards. more

  • Molecules in the mirror

    In 1871 the children‘s book “Through the Looking-Glass – And What Alice Found There” by the English author Lewis Carroll, in which Alice enters a world behind the mirror, was published. She explains to her cat: “First there’s the room you can see through the glass – that’s just the same as our drawing room, only the things go the other way. …How would you like to live in Looking-glass House, Kitty? I wonder if they’d give you milk in there? more
