The proposed device for determining the composition of the mixture of substances is as follows.

The ion source 2, consisting of the ionization chamber 3 and forms a pull electric field electrodes 4, 5, 6, 7, 8, 9, 10, converts a mixture of substances in a low-temperature plasma. In the ionization chamber 3 source 2 ions is heated molecules of the analyzed mixture of substances and the subsequent dissociation of molecules into positive and negative is 5, 7, 9 of the ion source 2 and then through the outlet 11 through holes are directed into the separator 14 positive ions. Negative ions are drawn by the electric field between the electrodes 5, 4, 6, 8, 10 ion source 2 and then through the outlet 12 through holes are directed into the separator 21 negative ions.

Derived from the ion source 2 through the outlet 11 through holes mixture partial positive ions enters the separator 14 positive ions in the space between the shell of the vacuum chamber 1 and the total for sockets 15, 16 wide part, to the beginnings of the longitudinal slot of the slots 17, 18 in the sockets 15, 16. The principle of operation of the separator 14 positive ions is that the separation of positive ions occurs at divergent magnetic barriers of the magnetic field. The magnetic barrier is shaped trough formed by the failure of the magnetic field in the longitudinal slot of the slots 17, 18. The magnetic barrier of the magnetic field along the short unbranched plot at the junction of the sockets 15, 16 are created by electric currents flowing through the sockets 15, 16, and therefore the magnetic barrier is easy to keep the partial positive ions in a single instant a circular orbit. As the movement of positive ion 17, 18 in the sockets 15, 16, i.e. in the region of divergence of the electric currents in the region of the magnetic field with divergent magnetic barriers and smaller values of the magnetic induction. In the separator 14 positive ions divergence of the magnetic barriers obtained through the largest gap between the side surfaces of the sockets 15, 16. Here, the electric current is greater socket 15 formed of a magnetic barrier that height, and magnetic induction is maintained at a level when the light beam of positive ions remains in orbit, located along the larger socket 15, and the heavy beam of positive ions coming down from orbit. The heavy beam of positive ions in this case is along the short section of straight-line trajectory, and then sent along a smaller socket 16. Retention of heavy beam of positive ions located along the smaller socket 16 orbit is another magnetic barrier. Retention of heavy beam of positive ions is sufficient value of the magnetic induction created a greater extent by an electric current flowing through the lower cowl 16, and to a lesser extent by an electric current flowing through the larger socket 15. Lowering mahaprajna along the smaller socket 16, on a straight trajectory. If you want positive ions to transfer from orbit, located along the smaller socket 16, in orbit, which is located along the larger socket 15, then increase the electrical current flowing along the larger socket 15. Derived from the ion source 2 a mixture of shared negative ions fed into the separator 21 negative ions. The separator 14 positive ions performs the splitting of the beams due to the largest splitting of the magnetic barriers along the slot of the slots 17, 18 when the asymmetric mutual position of the sockets 15, 16. The length of the separation zone of positive ions in this case is close to the minimum length. The separator 21 negative ions performs the splitting of beams of negative ions due to the largest splitting of the magnetic barriers along the slot of the slots 24, 25 in an asymmetric mutual position of the sockets 22, 23. The length of the separation zone of negative ions in this case is also close to the minimum length.

After the separator 14 light positive ions positive ions into the receiver 19, and the heavy positive ions into the receiver 20, and nakaplivayut 26, and the heavy negative ions into the receiver 27, and accumulate in the receivers. Receivers 19, 20, 26, 27 positive and negative ions function as electrodes in electrical circuits for measuring and recording the instantaneous ionic currents, as well as in electrical circuits, measure and record the total, negative and positive charges held in each branch of the circuit.

The invention, in comparison with the known technical solutions in this area, significantly increases the possibility of simultaneous determination of the composition of the positive sign of the electric charge of ions and negative in sign of the electric charge of the ions, as it uses to determine the composition of substances of all kinds of electric charges. At the same time, the present invention extends the capabilities of the weighting method to determine the composition of substances due to accumulation divided by the mass of chemical elements in the receivers ions.
