Claim:
1. A characterisation system comprising: a characterisation cell for smoke analysis by optical spectrometry, comprising: a collector downstream of the outlet orifice of the cell configured to recover the smoke after its analysis; a pressure regulator for keeping the pressure constant in the reaction chamber of the cell, wherein the pressure regulator comprises a regulation valve placed downstream of the collector to compensate for a loss of charge due to clogging of filters of the collector, wherein the regulation valve is connected to a pressure probe placed in the cell for measuring the pressure therein for its servo-control, and wherein the regulation valve is servo-controlled as a function of the pressure measured inside the cell and which is adapted to open progressively as the collector gets clogged; a reactor for the generation of smoke; a second collector positioned downstream of the reactor; a second regulation valve for regulating the pressure inside the reactor; wherein the second regulation valve is placed downstream of the second collector, wherein the second regulation valve is connected to a second pressure probe placed in the reactor for measuring the pressure therein for its servo-control, and wherein the second regulation valve is servo-controlled as a function of the pressure measured inside the reactor and which is adapted to open progressively as the second collector gets clogged.
