The MS7-100 quadrupole mass spectrometer is intended for analysis of gas mixture chemistry, and in particular, for measurement of exhaled air component concentrations, and their real time identification (during the breathing cycle). This mass spectrometer enables: measurements of human and animal breathing components, fast-response assessment of the environment status, monitoring of gas emission in industrial processes. The mass spectrometer is provided with a capillary sample admission system enabling measurements at distances of up to 5 meters away from the instrument. The sample flow rate is up to 10 ml/min. The admission system may provide preheating as an option. The MS7-100 mass spectrometer may be supplied complete with a multicapillary admission system for sequential monitoring of the chemistry of samples located at several places. In this case, the length of individual capillaries of the multicapillary system may reach 100 m. The instrument is started, switched to its operating mode, and deactivated fully automatically. The measurement procedure is controlled from a personal computer. Special software was developed for analysis result processing. We offer two modifications of the mass spectrometer, a basic model and a high-sensitivity model (turbo model). For the basic model, the vacuum system is supplied with a steam-oil pump, and for the high-sensitivity model, with a turbo molecular pump. The instrument may be used in medicine, ecology, production, and geology for both mass analyses and scientific research. The design of the MS7-100 mass spectrometer and its relatively small dimensions enable its use in mobile monitoring/analytical laboratories.
High sensitivity to all impurities (up to1 ppm). Fast-response noninvasive diagnostics of patients' state of health. Simultaneous real-time measurement of concentrations of various ambient air impurities. May be used in mobile laboratories for fast-response monitoring. Convenient software, and up-to-date algorithms of real-time measurement result processing. The instrument does not require expendables. No home analogs of the instrument are known.
Medicine: analysis of trends of the patient's breathing main component concentration; diseased condition diagnostics by metabolic products exhalation; sanitary and epidemic control monitoring. Ecology: detection and identification of organic impurities in the air, e.g. hydrogen sulfide, methane, hydrocarbons etc. Industry: industrial process harmful emission control by toluene, benzene, styrene etc. content in the air. Monitoring of the chemistry of incoming and exhaust gases in oxygen converter processes. Production of ultrapure gases.
