Abstract:
The measurement is carried out by a device of two non- dissociable measurement chains resulting in a continuous measurement which is representative of the total concentration of tars (even as traces) of a hot gas. It involves coupling of methods including one, SPME/GC/MS/PID, which is discontinuous and a priori partial, the other, PID, which is continuous but difficult to interpret alone. It is based on on-line processing of the elements transmitted by each of the measurement methods used. A tar generator (28) allows calibration of the apparatuses and calculation of the different coefficients required.
