Abstract: A cooling unit (cryo-focus unit) cools breath introduced into a carrier gas from a sample introduction unit, to trap volatile components in the breath into a column. A heater heats the volatile components trapped in the column to desorb the volatile components. Amass spectrometry (MS) section detects the volatile components desorbed by the heater and separated in a process of passing through the column. The breath introduced into the carrier gas from the sample introduction unit is cooled by the cooling unit, whereby more volatile components in the breath are trapped, and those volatile components can be desorbed, and can be detected by the MS section.
