In SRC I it was established that Ti, V, As, Ga, Fe, Zn, and Se showed distinct organic affinity and that these elements were probably present as metal-organic complexes or complexed in the asphaltene or preasphaltene structure.

An advantage of TTFA is its ability to produce reliable quantitative results with a minimun of prior knowledge. In order to further explore the utility of this approach, a data set consisting of physicall
