An electrostatic ion trap or an array of electrostatic ion traps are provided having a longitudinal length of no more than 10 mm and/or at least one electrode with a capacitance to ground of no more than 1 pF. First and second sets of planar electrodes may be distributed along the longitudinal axis, at least some of the which are configured to receive an electrostatic potential for confinement of ions received in the space between the first and second sets of planar electrodes. An array may comprise an inlet for receiving an ion beam, configured such that a portion of the ion beam can be trapped in each of the ion traps. Signals indicative of ion mass and charge data may be obtained from multiple electrostatic ion traps in the array. This mass and charge data may be combined for identification of components of a mixture of different analyte ions.

A quadrupole is filled with ions and the ions are cooled by applying a pressure and gas flow within the quadrupole. Ions are trapped in the quadrupole by applying a DC voltage and an RF voltage to quadrupole rods of the quadrupole, one or more DC voltages to a plurality of auxiliary electrodes of the quadrupole, and a DC voltage and an RF voltage to an exit lens at the end of the quadrupole. The ions are coherently oscillated after the filling and cooling by applying a coherent excitation between at least two rods of the quadrupole rods. The coherently oscillating ions are axially ejected through the exit lens and to a destructive detector for detection by changing one or more voltages of the one or more DC voltages of the plurality of auxiliary electrodes and changing the DC voltage of the exit lens.

An objective of this invention is to conduct an accurate quantitative analysis on the Ar element contained in a sample gas by an element analysis device comprising a heating furnace and a mass spectrometer for conducting a quantitative analysis on an element in a vacuum atmosphere. The element analysis device comprises: a heating furnace that heats a graphite crucible containing a sample while introducing a carrier gas into the heating furnace, thereby vaporizing the sample to generate a sample gas; a quadrupole mass spectrometer that conducts the quantitative analysis on the Ar element contained in the sample gas in a mixed gas comprising the carrier gas and the sample gas discharged from the heating furnace, a first pressure regulator that controls the pressure of the carrier gas to be introduced into the heating furnace, and a second pressure regulator that controls the pressure of the mixed gas discharged from the heating furnace.

A central hole is open in the side plate of the main substrate that the charged particles enter. The charged particles enter the mass analysis room through the central hole formed in the first main substrate.

A system for trapping an ion, including one or more lane elements in a substrate, one or more direct current (DC) elements in the substrate and connected to an electrode controller, one or more radio frequency (RF) electrodes, an RF controller connected to the one or more RF electrodes and configured to provide an RF signal to the one or more RF electrodes, one or more magnetic coils each having a portion associated with at least a portion of a DC element of the one or more DC elements and configured to be superconductive below a critical superconducting temperature, and a magnetic coil controller connected to each magnetic coil of the one or more magnetic coils, where the magnetic coil controller is configured to control the superconductivity and the magnetic flux of each magnetic coil of the one or more magnetic coils in relation to a source magnetic field.

An RF voltage is applied across each electrode of a first array of evenly spaced, parallel, and coplanar electrodes and its corresponding electrode of a second array of evenly spaced, parallel, and coplanar electrodes. The RF voltage varies in amplitude according to an RF voltage amplitude gradient. The RF voltage produces an array of different quadrupole RF electric fields in a uniform gap between the first array and the second array. A DC voltage is superimposed on each electrode of the first array and its corresponding electrode of the second array. The DC voltage varies according to a DC voltage gradient in order to produce a DC electric field in the uniform gap. When ions are introduced in the uniform gap, the DC electric field causes the ions to drift toward quadrupole RF electric fields with increasing RF voltage amplitudes where the ions are trapped according to their m/z.
