  • Ionization mass spectrometry method and mass spectrometry device using same
    Patent number: 10629421
    Abstract: A mass spectrometry device includes a sample seating part including an ultrasonic vibrator having a through hole through which liquid particles formed by the ultrasonic vibrator from an adsorbent material including a sample and a solvent are discharged, the adsorbent material being seated on the ultrasonic vibrator; a reaction part in which plasma or an ionization medium generated by plasma come into contact with the liquid particles discharged from the through hole to form an ionized material; an introduction part discharging and introducing the ionized material to a detection part; and the detection part analyzing the ionized material discharged from the introduction part. The mass spectrometry device and the mass spectrometry method can detect the components of various samples by converting a sample into liquid particles using ultrasonic waves and applying plasma and can detect samples in various fields without regard to locations.
