Development of miniature mass spectrometer and automated sampling explosive detector
We have been developing mass spectrometry techniques for safety and security of social infrastructures. Current trace detection such as for explosives detection and illicit drug testing contains the processes of swab-sampling and ion mobility detection, which results in the human-laboring, time-consuming, and high false alarm rate. To solve these problems, we developed high-throughput explosive detector, which consists of field-deployable linear ion trap mass spectrometer and automated particle sampling using cyclone separator. This instrument has been proved to achieve high-through detection of less than 3 second with a low false alarm rate of about 0.1%.
