EDS在陨石中的应用
Non-destructive sample analysis with high spatial resolution can be very difficult to accomplish using conventional EDS detectors as sample surface charging, electron beam damage and shading effects by topography are common problems in scanning electron microscopy. The BRUKER XFlash® FlatQUAD silicon drift detector (SDD) overcomes these limitations. The special geometry with an annular arrangement of detector elements offers a very high solid angle [1]. The XFlash® FlatQUAD detector allows the use of ultra-low beam currents and the investigation of samples with complex topography as demonstrated on two meteorite fall samples.
