Substance analyzer and substance analysis method

A substance analysis method, wherein:

• a storage unit is provided to store analysis timing information in which an elapsed time measured based on a time at which a medium is inserted into a medium heater is associated with information regarding for which chemical substance a tandem mass spectrometry is performed at the elapsed time, the analysis timing information being based on data on the chemical substance obtained in advance with a temperature rise of the medium heater that is consistent, and
• the substance analysis method includes:
• heating, by the medium heater, a medium for collecting a chemical substance adhering to a surface of an inspection object;
• causing, by a controller, a tandem mass spectrometer to perform, based on a temperature of the medium in the medium heater, tandem mass spectrometry for a chemical substance that is vaporized at the temperature of the medium using vapor sent from the medium heater to the tandem mass spectrometer by:
• measuring a heating time of the medium heater based on a time at which the medium is inserted into the medium heater;
• and instructing, in response to the measured heating time reaching the elapsed time in the analysis timing information, the tandem mass spectrometer to perform the tandem mass spectrometry for the chemical substance that is associated with the elapsed time in the analysis timing information;
• and
• performing, by the tandem mass spectrometer, the tandem mass spectrometry for a chemical substance as instructed by the controller by performing the tandem mass spectrometry for the chemical substance that is associated with the elapsed time.
