Factors, arising from the composition of the matrix, for multiplying the quotient of the measured intensity and the appropriate sensitivity factor in formulae to determine the composition using surface analytical techniques.
Note: In methods such as
Auger electron spectroscopy, the matrix factor is determined in part by the composition of the sub-surface material and in part by the composition of the analysis volume in the sample.
