| Zusammenfassung: | The present invention is directed, in general, to a method of testing an unknown sample with an analytical tool and, more specifically, a method of testing an unknown sample with an analytical tool specifically chosen, after determining the detection limit and calibration associated with the tool, for a particular matrix.
The present invention provides a method of testing an unknown sample with an analytical tool The method may include calibrating an analytical tool to a calibration standard having a known concentration of an element therein and obtained with a focused beam, thereby to achieve a calibrated analytical tool, determining an unknown concentration of the element within the unknown sample with the calibrated analytical tool, and correcting the unknown concentration with the calibration standard. |
