  • Coupling of liquid chromatography with mass spectrometry by liquid sample desorption electrospray ionization (DESI)
    Patent number: 8648297
    Abstract: An apparatus to separate and analyze components of a liquid sample include a high performance liquid chromatograph with a mass spectrometer utilizing desorption electrospray ionization. This permits separation and evaluation of different components in a liquid sample. Further, this can be combined with online derivation via reactive DESI and, further, can be used with further electrochemistry.
    Type: Grant
