摘要： A mass spectrometer has an atmospheric pressure chemical ionization source that includes a first ionization portion including a needle electrode, for generating a primary ion by discharge of the needle electrode a primary ion introduction aperture, and a second ionization portion including an introduction aperture, for generating a sample ion by the reaction between the primary ion and the sample gas introduced from an end of a column of gas chromatography, a sample ion movement aperture; and a mass analysis portion; wherein the end is arranged at a position satisfying the relation r≦2R where R is a radius of an inner diameter of the aperture and r is a distance between an axis connecting the center of the aperture and the center of the aperture, and the end.
