    摘要: Simulation of the collisional cooling effect using binary and ternary buffer gas mixtures in the ion trap mass spectrometer was per-formed using the SIMION 6.0 program, in which a 3D collision model was used to describe the ion–buffer gas collisions. Computation of the ion kinetic energy based on the Langevin theory under various conditions was used to account for the effects of mixed buffer gases on ion-collisional cooling. The addition of small amounts (8–9%) of one or two heavier target gases (nitrogen, argon or SF 6) to the 1 mtorr helium buffer gas in the ion trap can greatly improve the collisional cooling effects. The kinetic energy of ions can be reduced to close to 0 eV. Although the use of ternary buffer gas mixtures can also effectively improve the collisional cooling effects, the use of binary buffer gas mixtures is the better choice due to convenience and lower cost in real ion trap applications.
