  • Method for determining boron isotopic composition by PTIMS—static double collection
    Patent number: 8558166
    Abstract: A method for determining boron isotopic composition by PTIMS (Positive Thermal Ionization Mass Spectrometry)-static double collection realizes simultaneous static collection of m/e309 peak and m/e308 peak by double Faraday cups through adjusting the two parameters Focus Quad and Dispersion Quad in Zoom Optics, and completes high-accuracy determination of boron isotopic composition. The method includes (1) determining Focus Quad and Dispersion Quad parameters in the Zoom Optics of the ion source; (2) determining the two parallel cups in the Faraday collector and their parameters; (3) determining the collection mass number of the center cup of the Faraday collector.
