摘要

The utility model relates to analytical instrument engineering for research and analysis of substances and can be advantageously used for the detection and identification of trace amounts of low-volatile organic compounds, especially drugs, explosives, psychotropic, toxic or environmentally hazardous substances using ion mobility spectrometry equipment.; The spectrometer comprises a ionization chamber with inlet and outlet nozzles for the analyzed samples of air and a source of the corona discharge as a ionization source chamber ion drift to the collector electrode, articulated with the ionization chamber, a first valve provided between the ionization chamber and the ion drift, a second shutter which configured to pass ultraviolet optical radiation, such as a metal mesh or a perforated metal plate, and is mounted between the sources com corona discharge and inlet and outlet port, and source voltages to the electrodes connected to the source of the corona discharge, the first and second gates and the collector electrode and adapted to changes applied to the first gate voltage, and to supply the second gate voltage, which locking relative to ions of the same sign as the ions, molecules detectable substance.; The utility model provides a reduced probability skip trace amounts of organic substances detected. 1 bp f-ly, ZP 2 f-ly 1 Fig.; The utility model relates to analytical instrument engineering for research and analysis of substances and can be advantageously used for the detection and identification of trace amounts of low-volatile organic compounds, especially drugs, explosives, psychotropic, toxic or environmentally hazardous substances using ion mobility spectrometry equipment.; The spectrometer comprises a ionization chamber with inlet and outlet nozzles for the analyzed samples of air and a source of the corona discharge as a ionization source chamber ion drift to the collector electrode, articulated with the ionization chamber, a first valve provided between the ionization chamber and the ion drift, a second shutter which configured to pass ultraviolet optical radiation, such as a metal mesh or a perforated metal plate, and is mounted between the sources com corona discharge and inlet and outlet port, and source voltages to the electrodes connected to the source of the corona discharge, the first and second gates and the collector electrode and adapted to changes applied to the first gate voltage, and to supply the second gate voltage, which locking relative to ions of the same sign as the ions, molecules detectable substance.; The utility model provides a reduced probability skip trace amounts of organic substances detected. 1 bp f-ly, ZP 2 f-ly 1 Fig.
