Provided is a portable gas chromatograph-mass spectrometer (GCMS) capable of quantitatively/qualitatively analyzing volatile organic compounds in the air up to an infinitesimal amount in real-time, more particularly, to the portable GCMS for monitoring volatile organic compounds in real time which integrally includes a Gas Chromatograph (GC) including a sampling device into which volatile organic compounds are injected, a small-sized gas chromatograph module, and a nitrogen supply source for supplying carrier gases of the gas chromatograph module; a Mass Spectrometer (MS) including a vacuum chamber and a quadrupole mass spectrometer included in the vacuum chamber; and a GCMS interface connecting the GC and the MS, as is constituted in one body. The portable GCMS is easy to use on the spot, minimizes the consumable parts, detects promptly in real-time on the spot. |
