Abstract
The device measures a light in a liquid by introducing in the liquid at least one emitting probe. The emitting probe includes a transmitter connected to a first waveguide, a second waveguide, and included in the second waveguide, at least one reflecting surface. The device may be used in a method for measuring the flocculation threshold of a colloidal medium by gradually adding apolar solvent. The method includes a step which of determining, using at least one probe of the device, flocculation after adding amount of apolar solvent required for flocculation. The method is applicable to asphaltenes. The device may be used for measuring physico-chemical properties in opaque media.
