    • The invention relates to methods and devices for measuring daughter ion spectra (also called fragment ion spectra or MS/MS spectra) in time-of-flight mass spectrometers with orthogonal injection of the ions. The invention filters the parent ions selected to be fragmented by a mass filter before they are injected into the time-of-flight mass spectrometer, fragments the selected ions in a first stage of the time-of-flight mass spectrometer within a collision cell filled with collision gas at collision energies between one and five kiloelectron-volts, further accelerates the fragment ions and measures the fragment ions in a second stage of the time-of-flight mass spectrometer.

    • In a mass spectrometer having an ion source in which analyte substances are ionized by matrix assisted laser desorption and form an ion beam that travels to a parent ion selector for selecting ions to form daughter ions, the ion beam is reflected in at least one reflector prior to the parent ion selector so that only ions that have both the mass of the parent ions and their kinetic energy are allowed to pass to the parent ion selector. By taking this measure, the mass resolution in the daughter ion spectra is also increased; the improved mass resolution and improved signal-to-noise ratio produce higher sensitivity, even though fewer ions are admitted for analysis in the daughter ion spectrum.

    • The invention relates to the cleaning of contaminated accelerating or guiding electrodes of ion sources used for ion generation by desorption. A cleaning plate is used that has an outer contour similar to that of a standard sample support plate, and may be equipped with cleaning scrubbers that can be moved out when necessary to contact the electrodes. The scrubbers may include soft covers, and can carry out the cleaning by dry rubbing or with the help of high-boiling solvents for the matrix substances. The moving out of the cleaning scrubbers can be controlled by external light pulses from a laser or video camera spot light. Alternatively, the cleaning plate may be equipped with spray nozzles connected to a reservoir of cleaning fluid which is sprayed onto the electrodes, and the evacuation of the ventilated ion source chamber may be used to initiate the spraying.
