PROBE FOR MEASURING LIGHT IN A LIQUID, PROBE FOR DETECTING THE FLOCCULATION THRESHOLD OF A COLLOIDAL MEDIUM, RELATED DETECTION METHOD AND USE FOR DETERMINING THE FLOCCULATION OF ASPHALTENES

摘要

a transmitter connected to a first waveguide; a second waveguide; and included in said second waveguide, at least one reflecting surface. The invention also concerns a method for measuring the flocculation threshold of a colloidal medium by gradually adding apolar solvent using the inventive device, comprising a step which consists in determining, using at least one probe of said device, flocculation after adding the amount of apolar solvent required for flocculation. The invention is applicable to asphaltenes. The invention also concerns the use of said device for measuring physico-chemical properties in opaque media. Fig. 2
