Quantitative analysis of a bulk sample requires that the composition of the sample is homogeneous over the analyzed volume. For inhomogenous samples the calculation of the matrix effects is not correct and this can lead to wrong results in the element concentrations. For samples containing a layer structure a different quantitative evaluation has to be applied. This can be provided with the standard-based analysis in ESPRIT in combination with the STRATAGem software.
The advantage of the use of STRATAGem in combination
with Bruker ESPRIT is:
A wide range of variables can be set to fixed values or
used as fit parameters. Result graphs can be directly
checked for agreement,
The open model provides a flexible setup of the sample
structure,
Graphs of K ratios vs. HV or K ratios vs. thickness can be
generated.
This method is good for the analysis of layers with thicknesses
ranging from some nm to a few μm, depending on HV
and type of layer. It also provides accurate results for multilayer
structures.
