Abstract:
1. A mass spectrometry system for continuous control of environment by detecting a source of contamination comprising: system carrying means; a sampling unit installed in said system carrying means having sample extraction means for extracting samples from said environment, said sampling unit having an output; an ionization device connected to said output of said sampling unit and supported by said system carrying means, said ionization device forming a beam of ionized particles from said samples, said ionization device having an ionization device input and an ionization device output; a time-of-flight mass spectrometer, which is supported by said system carrying means and has a mass spectrometer input, mass spectrometer output, and a deflector modulator connected to said ionization device output for alternatingly deflecting said beam of ionized particles with a predetermined angle for dividing said beam of ionized particles into two independent flows guided along two independent trajectories; and a data acquisition and analysis unit that acquires data from said sampling unit, said ionization device, and said time-of-flight mass spectrometer, said data acquisition and analysis unit having means for analysis of said data and for generating control data that controls and monitors operations of said sampling unit, said ionization device, and said time-of-flight mass spectrometer.
