High Sensitivityɹ− Improves Lower Detection Limit by Up to 6 Times −
In metals analysis, the lower detection limit of trace elements in main components has been improved.
Guide of the Lower Detection Limit (300 sec) for Lead in Metals
[ppm]
EDX-7200 EDX-7000 EDX-720
Copper alloy 9.9 17.1 35.5
Solder 3.9 8.4 24.8
Aluminum alloy 0.7 1.1 3.3
Note: The detection limit is an example and not a guaranteed value.
High Resolution
EDX-7200 offers superior energy resolution compared to EDX-7200 Previous model
previous models by incorporating a state-of-the-art SDD (EDX-720)
detector.
This reduces the effects of overlapping peaks of different
elements, enhancing the reliability of the analysis results.
Comparison of Energy Resolutions (sample: PPS resin)
No Liquid Nitrogen Required
The SDD detector is capable of electronic cooling. Since there is no need to use liquid nitrogen, it reduces running costs.

ɾ An optional vacuum measurement unit or helium purge unit is required to measure light elements (15P and below) with the EDX-7200.
ɾ Lower detection limit varies depending on the sample matrix or coexisting elements.
ɾ Lower detection limit of light elements (20Ca and below) gets worse when the sample cell film is used.
