X- ray experimental set-up for in-vitro nail test

In this investigation, the elements Ca and S were evaluated in a single nail clipping using compact portable X-ray spectrometer model X-123 SDD with Ag target. Experimental conditions for current, voltage excitation time investigated. These analyses can be useful variety of applications, including nutritional medical diagnosis, such as, evaluation bone dysfunctions by measurement (bone decalcification) nutrition evaluations (collagen production). This analysis offers some benefits comparatively to blood serum analyses, non-invasive collection, fast (minutes) low cost. addition, clippings are simple obtain, easy store, transport. pilot study show positive expectation clinical application in-vitro test.
