Abstract: A method for performing mass spectrometry by causing a precursor ion derived from a sample component and a radical to react in a reaction chamber 132 to generate products ion from the precursor ion, the method including: a step 6 of generating a radical from a material gas; a step 8 of introducing the radical and the precursor ion into the reaction chamber 132 in a state where an amount of electric power corresponding to a generation condition of the radical is supplied to a temperature control part 1331 provided in the reaction chamber 132; and a step 9 of separating and detecting product ions generated from the precursor ion in the reaction chamber 132 according to a mass-to-charge ratio.

Abstract: In the non-volatile storage unit (341) of the local control unit (34) of each unit (3 to 6) configuring an LC system, periodic inspection information, such as the installation date and the next inspection scheduled date, is stored at an appropriate time. When an analysis is carried out, in the system control unit (2) which controls each unit, a periodic inspection notification processing unit (211) collects periodic inspection information from each unit (3 to 7) upon power on or start up, compares the next inspection scheduled date with the current time by the real-time clock (212), and determines a unit for which a periodic inspection notification is required. If there is a unit that requires a periodic inspection notification, a notification request is sent to the unit, and the local control unit (34) of the unit outputs an indication prompting periodic inspection to the display unit (35). As a result, even if the installation times are different for each unit and even if each unit does not have a real-time clock, it is possible to notify a user when a predetermined age of service has passed from the installation time of a given unit.
