There is provided an element mapping unit, scanning transmission electron microscope, and element mapping method that enable to acquire an element mapping image very easily. On the scanning transmission electron microscope, the electron beam transmitted through an object to be analyzed enters into the element mapping unit.

Because the acceleration voltage data for each element and window data for 2-window method, 3-window method or contrast tuning method are already stored in a database and accordingly the spectrum measurement is carried out immediately even when an element to be analyzed is changed to another, the operator can confirm a two-dimensional element distribution map immediately. Besides, because every electron beam that enters into an energy filter passes through the object point, aberration strain in the electron spectrometer can be minimized and higher energy stability can be achieved. As a result, drift of the electron energy loss spectrum acquired by analyzing the electron beam into spectrum can be minimized and element distribution with higher accuracy can be acquired.
US07928374B2 Resolution improvement in the coupling of planar differential mobility analyzers with mass spectrometers or other analyzers and detectors
Prior work on differential mobility analysis (DMA) combined with mass spectrometry (MS) has shown how to couple the output of the DMA with the inlet of an atmospheric pressure ionization mass spectrometer (APCI-MS). However, the conventional ion inlet to an APCI-MS is a round orifice, while conventional DMA geometries make use of elongated slits. The coupling of two systems with such different symmetries limits considerably the resolutions attainable by the DMA in a DMA-MS combination below the value of the DMA alone. The purpose of this invention is to overcome this limitation in the case of a parallel plate DMA. One solution involves use of an elongated rather than a circular MS sampling hole, with the long dimension of the MS inlet hole aligned with that of the DMA slit. Another involves use of a more elongated orifice in the DMA exit and a more circular hole on the MS inlet, the two being connected either through a short transfer conduit or through an ion guide. The DMAs described can also be coupled profitably to detectors and analyzers other than mass spectrometers.

When ions are introduced, a voltage applied to the electrode unit 11 is put to zero to release the sector-shaped electric field E1. Then the ions emitted along the ion-introduction orbit 5 fly straight in the electrode unit 11. The direction and position of the ions coming out from the exit end of the electric field is the same as those ions flying along the loop orbit 4. Therefore, there is no need for placing a deflection electrode for introducing/leading-out ions on the loop orbit.
