Abstract (en)
[origin: WO2006064132A1] The invention concerns a device (I) for mass analysis of molecules comprising a quadripole ion trap (1) provided with an input (2) for injecting molecules in ionized form to be analyzed and an output (3) for ejecting ions to be detected, including a system of electrodes (4) enabling a three-dimensional quadripole field to be generated, capable of trapping the molecules in ionized form to be analyzed, based on their mass over charge ratio (m/z) in a trapping volume (5), said trap (1) being coupled to a UV or visible laser beam (L) dissociating the molecules to be analyzed. The invention is characterized in that the laser beam (L) is introduced into the trap, without passing through an optical fiber via an opening (13) provided in one of the electrodes, different from the input (2) and the output (3) and sealed by a porthole allowing through the laser beam, the dimension of the porthole (14) being selected so that the laser beam covers the entire trapping volume. The invention also concerns a mass analysis method, with laser beam dissociation.
