Abstract: In a mass spectrometer, a detector generates a current-pulse signal corresponding to an incident ion, with a gain corresponding to a detector voltage which is given by a voltage-generating section. A branching section divides, into branches, a voltage-pulse signal which is based on the current-pulse signal taken from the detector's anode. A pulse-counting section detects the signal one branch by a pulse-count method. An analog detection section detects the signal in another branch by an analogue detection method. A conversion-information storage section holds conversion information showing a relationship between an unsaturated predetermined pulse-count value and the corresponding analog detection value under the detector voltage given to the detector during a measurement.

Abstract: An orthogonal acceleration electrode (242) deflects the flight direction of ions incident from an ion source (201). A flight-path-defining electrode (244, 246, 247) defines a flight path of the deflected ions. An ion detection section (245) detects an ion after the flight of the ion through the flight path. A voltage application section (3) applies voltages to the orthogonal acceleration electrode and flight-path-defining electrode. A measurement control section (43) acquires mass spectrum data by conducting a measurement of a known ion generated from a predetermined amount of known sample, under a plurality of measurement conditions which differ from each other in the value of the voltage applied to the orthogonal acceleration electrode. A score-value calculation section (44) calculates a score value based on a predetermined calculation formula, using the intensity of a mass peak and the mass-resolving power in the mass spectrum data acquired under each of the measurement conditions.

Abstract: A matrix-derived peak information acquisition unit (31) creates a peak list that summarizes various ions derived from a matrix and their theoretical m/z values based on a result of analysis of a sample of only a matrix, and stores the peak list in a matrix-derived peak information storage unit (32).
