摘要： An API (Atmospheric Pressure Interface) ion source and a mass spectrometer with the same are disclosed. In the disclosed API ion source and the mass spectrometer with the same, the included angle α between the capillary (2) and the mass analyzer (4) of the mass spectrometer (10) is 80°˜150°. The repeller electrode (3) is installed outside the included angle a and a 110˜380V DC voltage is applied thereto, so that the sample ions with low kinetic energy in the sample ion flow passed through the capillary (2) change the flying direction thereof by an angle with 180°-α and subsequently enter the mass analyzer (4).
