Mass spectrometer |
摘要 |
A semi-micro liquid chromatograph/mass spectrometer apparatus has an ion source. The space from the end portion of a flow passage of a liquid chromatograph shell to a vaporization portion is closed so as to prevent the inflow of a gas from outside the ion source into the space. Further, the nebulization and vaporization portions are joined together and heated by a common heater. Dilution of a sample to be analyzed is prevented, and high sensitivity detection becomes possible in a low velocity liquid chromatograph/mass spectrometer.
