Title: MASS SPECTROMETRY DEVICE AND MASS SPECTROMETRY METHOD
Abstract:
This mass spectrometry device is equipped with a mass spectrometer 2, a mass spectrum generation unit 31, an absolute intensity comparison unit 32, a peak pattern comparison unit 34, and a target component determination unit 35. The mass spectrometer 2 subjects a specimen to mass spectrometry by direct ionization. The mass spectrum generation unit 31 generates a mass spectrum on the basis of the mass spectrometry from the mass spectrometer 2. The absolute intensity comparison unit 32 compares a threshold with the absolute intensity of a peak included in the mass spectrum generated by the mass spectrum generation unit 31. The peak pattern comparison unit 34 compares a pre-set peak pattern and the mass spectrum generated by the mass spectrum generation unit 31 with one another. The target component determination unit 35 determines whether a target component is present in the specimen or not, on the basis of the comparison results from the absolute intensity comparison unit 32 and the comparison results from the peak pattern comparison unit 34.
