In the case of LaB6 for quantitative analysis

Six boride lanthanum (LaB₆) is one of the S/TEM quantitative EDS analysis very illustrative example, because it contains two extremes, a very light elements (B) and a heavy elements (La).LaB₆Can be used to display brooke XFlash ® detector and Cliff - Lorimer performance of quantitative method.

Quantitative test starting element identification of unknown samples.To quantitative element can be defined automatically or interactive manner.Elements from stray radiation energy peak, for example, the sample rack Cu network or carbon pollution is used only for solution of convolution.The next step is to buckle the bottom of the back, we have provided a special kind of bremsstrahlung physical model, with perfect fitting the actual back end.The third step is the convolution spectrum peaks, stripping solution, software provides several different fitting model can be used to implement the best peak separation.Finally, using the theory or calibration Cliff - Lorimer (CL) complete quantitative factors.

LaB₆The prototype (spectrum turquoise in the atlas of the spectrum) Cliff - Lorimer of calibration factor can be used in the experiment.

Using the theory of CL factor results have shown that the excellent properties of brook Cliff - Lorimer quantitative.They are very close to the expected a La at % 14.29 and B 85.71 at. %.In addition, the use of La quantitatively and the results show that the K series instead of L QUANTAX system is very suitable for spectra collection, line is also very suitable for more than 20 kv peak of quantitative.
