PROBLEM TO BE SOLVED: To solve the problems wherein analysis of an extremely small amount of component is difficult in the case of analysis of a sample including various kinds of components because the kinds of materials capable of tandem mass spectrometry are limited, in a background wherein the extremely many kinds of materials are sometimes mixed in an extraction sample from a living body and the amount (concentration) of each material is sometimes different in many figures. SOLUTION: In this device having an internal database wherein mass information of ions and a retention time are stored, mass spectrometry or the tandem mass spectrometry is executed, while performing automatic correction in an execution process of analysis relative to information in the database.
