Once gas chromatography (GC) separates a sample into its component parts, a detector identifies them. All detectors provide certain benefits and struggle with some limitations. Whether some feature is beneficial or detrimental, however, depends on the sample and the application.
A century ago, physicists used a tabletop “cloud chamber” to explore the motion of otherwise invisible particles. Today, they need giant machines to explore the bizarre frontiers of modern physics.
Kansas State University engineers have developed a lithium-based neutron detector that is being recognized as one of the year's Top 100 newly developed technologies.
