DESKTOP QUADRUPOLE MASS SPECTROMETER MS7-800

 

 

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.

 

 

 

 

 

Peculiar features

•  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.
