EurekAlert  August 29, 2019 Paper spray mass spectrometry is a rapid and sensitive tool for explosives detection but so far it has only been demonstrated using high resolution mass spectrometry, which bears too high a cost for many practical applications. Researchers in the UK developed a system which uses swabbing material, they call “swab spray” to collect explosives from surfaces. Sensitive detection using swab spray will require a mass spectrometer with a mass resolving power of 4000 or more. The new detection method is able to analyse a wider range of materials than current thermal based detection systems used in […]
