Vitrinite reflectance measurements can be used to characterize the components within blends. Measures can be taken to correct for the vitrinite percentage within each of the components of the blend or to determine the proportion of components in a blend, particularly when the components have dissimilar vitrinite contents. This method necessitates the identification of vitrinite by the analyst.
Reflectance measurements on vitrinite obtained by interpreting the results from an automated system, are outside the scope of ISO 7404-5:2009.
