20090309015 | NEUTRAL/ION REACTOR IN ADIABATIC SUPERSONIC GAS FLOW FOR ION MOBILITY TIME-OF-FLIGHT MASS SPECTROMETRY - The content of the invention comprises a concept of reactor for isolated ion transformations induced by collisions with neutral species. This reactor is also an interface between mobility cell and orthogonal injection TOFMS based on supersonic adiabatic gas flow with variable controlled composition directed along the axis of a multipole ion guide with sectioned rods for possibility of creating of controlled distributions of RF, DC and AC rotating fields. | 12-17-2009 |
