A comparison of ion mobility spectrometry and direct ionisation mass spectrometry for the detection of trace explosives on hand swabs.

摘要

The data obtained shows similar performance for the ASAP-MS system to the traditional devices, dependant onoperation mode of the mass spectrometer and source conditions. It is felt that further refinement of the swabdesorption interface coupled to the MS would improve the usefulness of the technique. However the data presented demonstrates the potential of the ASAP-MS technology for security screening.
