Desktop quadrupole mass spectrometer MS7-800 with ionization by electron impact and mass range of 2 to 800 a.u. is designed for quantitative analysis of composition of gas mixtures and volatile liquid mixtures containing organic impurities with complex chemical composition.

•  Desktop embodiment of the quadrupole mass spectrometer.

•  Analytical characteristics are not worse than those of the world-best instruments of this class.

•  High analysis rate allows MS7-800 to be used (through a special interface) as a mass-spectrometric detector within a chromatographic/mass-spectrometric setup.

•  Gas analysis with instrument MS7-800; analysis of vacuum system residual gases, controlling gas purity in various manufacturing processes, atmosphere analysis.

•  Chemical analysis by using MS7-800 as a part of gas chromatograph/mass-spectrometer; analysis of a wide range of volatile organic compounds.
