Researchers from Sandia National Laboratories (Albuquerque, USA) and collaborators at Caltech have developed a low-power, ultra-high-speed, comprehensive GCxGC system, consisting of microfabricated columns, nanoelectromechanical system cantilever resonators for detection, and a valve-based stop-flow modulator. The researchers demonstrated that the system had a peak capacity greater than 50 compounds per second.
