  • Fourier transform ion cyclotron resonance mass spectrometer using a cryo-detection system
    Patent number: 8440966
    Abstract: A Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS) is provided. A preamplifier is installed as nearest to an ion cyclotron resonance (ICR) trap as possible at a detector part in the mass spectrometer, and thermal noise generated at the preamplifier is minimized by means of a cryo-cooling system to increase a signal-to-noise ratio of ion detection signals such that an ultra-low amount of specimen can be detected, which was impossible in the related art.
    Type: Grant
    Filed: December 29, 2008
    Date of Patent: May 14, 2013
    Assignee: Korea Basic Science Institute
    Inventors: Myoung Choul Choi, Yeon Suk Choi, Jeong Min Lee, Seung Yong Kim, Dong Lak Kim, Hyun Sik Kim, Jong Shin Yoo, Stefan Karl-Heinz Stahl
