  • Publication number: 20090242753
    Abstract: The invention relates to a device for mass analysis of molecules comprising a quadripolar ion trap equipped with an inlet for injection of molecules to be analysed in ionised form and an outlet for ejection of the ions to be detected, comprising an electrode system for generating a three-dimensional quadripolar field, capable of trapping the molecules to be analysed in ionised form, as a function of their mass to charge (m/z) ratio in a trapping volume, said trap being coupled to a UV or visible laser beam ensuring dissociation of the molecules to be analysed, characterised in that the laser beam is introduced to the trap without passing via fibre optics via an opening made in one of the electrodes, separate from the inlet and the outlet and blocked tightly by a viewing window allowing the laser beam to pass through, the dimension of the viewing window being selected such that the laser beam covers the entire trapping volume, as well as a process for mass analysis, with laser beam dissociation.
