Abstract
The disclosure relates to a cell for measuring the amount of insoluble particles in a fluid that comprises a duct that passes through the cell, a filter for the particles contained in the fluid, the filter being positioned in the duct, an emitter capable of emitting an electromagnetic beam directed towards the insoluble particles concentrated on the filter, and a receiver capable of receiving the electromagnetic beam emitted by the emitter and reflected by the insoluble particles concentrated on the filter. The disclosure also relates to a device comprising this cell, to a method for measuring the amount of insoluble particles in a fluid and to applications thereof, in particular to the study of the oxidation stability of petroleum distillates, to the antioxidant capacity of additives of petroleum products and to the determination of the asphaltene content of petroleum products.
