Description
Technical field
The utility model relates to the mass spectrometer field, is specifically related to a kind of mass spectrometric vacuum chamber system that is used for.
Background technology
Mass spectrometer claims mass spectrograph again, a kind of separation with detect different isotopic instruments, promptly according to charged particle can deflection in electromagnetic field principle, by the quasi-instrument that the mass discrepancy of material atom, molecule or molecular fragment is separated and detection material is formed.Mass spectrometer is a core with ion source, mass analyzer and ion detector.Ion source is to make sample molecule Ionized device under high vacuum condition.Molecule after the ionization is because of having accepted multiple fragment ion and the neutral particle that too much energy can further be fragmented into less quality.They obtain the mean kinetic energy with identical energy and enter mass analyzer under the accelerating field effect.Mass analyzer is to enter the ion of different quality wherein simultaneously, by the device of mass-to-charge ratio m/z size separation.Ion after the separation enters ion detector successively, gathers and amplifies ion signal, and machine is handled as calculated, is depicted as mass spectrogram.Ion source, mass analyzer and ion detector all respectively have polytype.Mass spectrometer is divided into isotope mass spectrometer, inorganic mass spectrometer and organic mass spectrometer by range of application; Be divided into high-resolution, middle resolution and Low Resolution Mass Spectra instrument by resolving power; Be divided into static instrument and dynamic instrument by operation principle.
Mass spectrometric vacuum degree is the key factor that influences ion motion speed, vacuum degree deficiency causes ion and gas molecule collision easily, thereby reduce the movement rate of ion, to the influence of corresponding relation between the signal of telecommunication of mass analyzer and the detector signal of telecommunication mainly is thereby that aspect such as embodiment time correspondence influences mass accuracy, and the ion motion rate variation that causes of vacuum degree deficiency also can influence mass spectrometric resolution simultaneously.But the problem of the design ubiquity vacuum degree deficiency of existing mass spectrometric vacuum chamber.
