Real-time air fingerprinting (RAFT) uses spectroscopic techniques to measure volatile organic compounds. Now, the University of Leicester in the UK is testing the use of RAFT for rapid and noninvasive diagnosis of illness in an emergency ward. Paul Monks, a professor in atmospheric chemistry and earth observation science, explains the approach.
