摘要

1. Transient Analyzer quadrupole mass spectrometer (the type of filter masses, "monopole", "tripole") containing the ions of a specific sorting unit charges formed in the form of four hyperbolic electrodes for the mass filter and "tripole" and two hyperbolic electrodes "monopole "input device analyte ions in the sorting device and an output device sorted ions from the sorting device, characterized in that the input and output device formed as two-electrode cells quadrupole cn individuality together with the quadrupole field to create a longitudinal (along the z-axis direction) uniform electric field, the electrodes are electrically insulated from each other, wherein the working surfaces of the quadrupole electrodes of cells are described in the working volume ratios within the cell: ! ! wherein y0 - «field radius" hyperbolic electrodes sorting apparatus, l - length of the two-electrode quadrupole cell with a longitudinal field, K0 - geometrical parameter of the electrode system quadrupole cell with longitudinal homogeneous field, defined in the design, the electrode described relation (1) electrically connected to one sorting device hyperbolic electrode, and the electrode described relation (2), and is grounded near the point y ~ 0, x ~ 0, z ~ 0 an aperture for input and output of the ions. ! 2. Transient Analyzer quadrupole mass spectrometer (the type of mass filter) according to claim 1, characterized in that the input device of the analyzed ions quadrupole comprises four two-electrode cell with a longitudinal homogeneous electric field, the electrodes all cells, describing
