Integrated ion focusing and gate lens system for ion trap mass spectrometer

摘要

Topic The background noise which is derived from the liquid drop which electric charge is done is made to decrease. SolutionsAre used in the ion trap mass spectrometer ion focusing and the gate conversion lens 26 which are unified cylindrical form the 1st and 2nd constitution body is included generally is combined, in this case, the aforementioned constitution body when being biased at the same voltage vis-a-vis the respective constitution body, generally makes the ion beam focus alongside the axis of cylindrical form, at the same time, the aforementioned constitution body when being biased at the voltage where the aforementioned constitution body differs, makes the ion beam deflect. In desirable execution form, the 1st and 2nd constitution body form is identical.
