The Iatroscan MK-6s Equipment is a chromatograph used to quantify the main components of asphalt binders: Saturated, Aromatic, Resins and Asphaltenes (SARA) through a Flame Ionization Detector (FID). The working principle is based on the Thin Layer Chromatography (CCD) technique. Initially, the asphalt binder is diluted in chloroform, and then injected into a column (Chromarod) using a microsyringe. This column (stationary phase) is coated with an adsorbent material. After the volatilization of the chloroform from the asphalt solution, the asphalt is adsorbed on the column, and the process of separating each component (SARA) begins due to its chemical affinity for the solvents and solvent mixture (called mobile phase), which permeate the column by capillary action. This equipment is used for materials that have high molecular weight and leave “residue in the columns” after completion of the test, which are difficult to be used in other chromatography techniques, such as Liquid Chromatography (LC) or Gas Chromatography (GC).

Stratura is a pioneer company in asphalt materials technology and has the Iatroscan MK-6s Equipment, a tool for the Research and Development of asphalt binders, making it possible to anticipate and know its behavior in relation to:

– old and aged floors;

– to new floors;

– modifications with different types of polymers;

– to short-term (RTFOT) and long-term (PAV) aging;

– to colloidal stability.
