ABSTRACT:
The present invention relates to a mass analyzing apparatus, comprising a first metal electrode plate, a second metal electrode plate, an RF power supply, a reactant gas and a mass spectrometry. The second metal electrode plate is grounded. There is a gap between the first metal electrode plate and the second metal electrode plate. The RF power supply is electrically connected to the first metal electrode plate. Electric discharge is caused between the first metal electrode plate and the second metal electrode plate, so that the reactant gas becomes dissociation plasma. The dissociation plasma reacts with a gas analyte from a sample and then enters the mass spectrometry for a mass analysis. In addition, since the dissociation plasma is generated under low temperature and atmospheric pressure, the mass analyzing apparatus of the present invention is applicable for biological samples that need to be analyzed at a low temperature.
