“…In a larger scale, curves are almost the same in the dilute regime but in the concentrated regime, the intensity decreases, showing that structure has changed. This has already been observed in [9].…”

“…Since asphaltenes are absorbent materials, these techniques are limited to dilute asphaltene solutions. The principle used in these techniques consists in measuring the brightness of the scattered beam against wavelength (λ) and angle of observation (θ) which define the wave vector Q according to: Espinat et al (1998) provide an exhaustive description of the information which can be deduced from scattering measurement. The results of such measurements can be divided into two types: those which are dependent on an interpretation model and those which are not.…”
