Matrix effects are processed with mathematical corrections. For each element, the upper limit of the concentration range covered by this test method is defined by the highest concentration listed in Table 1. Samples containing higher concentrations can be analyzed after dilution.

For each element, the lower limit of the concentration range covered by this test method can be estimated by either the limit of detection (LOD) or the limit of quantity (LOQ), both of which are 2. The repeatability can be estimated from the standard deviation of Sr.

LOD and LOQ are not intrinsic constants of this test method. LOD and LOQ depend on the precision a laboratory can achieve when using this test method.

This test method uses regression software to determine calibration parameters that may include effect coefficients (ie, inter-element effects coefficients), here referred to as alphas. Alphas can also be determined from theory using relevant software.

The setup of this test method is intended for persons trained in the practice of X-ray spectrometry. After installation, this test method can be used routinely.

Values ​​stated in SI units or angstrom (Å) units should be regarded as individual standards.
