Abstract: Ions ejected from a collision cell are detected by a detector. An evaluation unit generates a temporary calibration curve based on an intensity of a detection signal and evaluates an ion accumulation time of the collision cell based on the temporary calibration curve. When the evaluation unit determines signal saturation, the ion accumulation time of the collision cell is reduced. When the evaluation unit determines sensitivity insufficiency, the ion accumulation time of the collision cell is increased.

Abstract: A mass spectrometry data processing apparatus includes a computation unit and a seeking unit. The computation unit calculates the mass difference ?m/z between the peaks of two molecules selected from mass spectrum data or obtains the mass difference ?m/z. The seeking unit estimates a combination of atoms between the peaks of the two molecules in a range of the mass difference ?m/z. The seeking unit seeks the combination of atoms having a mass difference, which matches the mass difference ?m/z, between a set of atoms desorbed from a first molecule of the two molecules and a set of atoms added to the first molecule.

Abstract: An image generating apparatus capable of facilitating analysis of a substance having a repeating structure has: an ion intensity data acquisition portion for acquiring ion intensity data arising from the substance, the data including information about a relative intensity of each ion against mass-to-charge ratio; a mass information acquisition portion for acquiring mass information about the repeating unit of the substance; a data alignment portion for aligning the ion intensity data within each given range of mass-to-charge ratios based on the mass information about the repeating unit of the substance; and an image generation portion for generating an image based on the aligned ion intensity data.
