摘要
A method is disclosed for increasing the dynamic range and sensitivity of a quadrupole ion trap mass spectrometer operating in the chemical ionization mode. Prior to mass analysis, a prescan is performed with the ion trap and the ionization and reaction periods are adjusted to produce enough stored product or analyte ions to generate a good signal- to-noise ratio in the detection of trace amounts of analyte, yet not so many analyte ions that resolution in the mass spectrum is lost. A mass analysis scan is then performed with the ion trap using the ionization and reaction periods predetermined during the prescan.
