Patent ID: 8054082

Claim:
A device for continuous measurement of the total concentration of tars, which may even be in the form of traces, in a gas characterized in that it comprises: a first line for continuous measurement of the total amount of tars, by means of a photo-ionization or flame-ionization detector ( 32 ), a second line for sequential measurement of the total amount of tars successively including means for extracting and concentrating the tars present in the gas ( 12 , 13 ), means for separating different species of tars concentrated previously ( 25 ), means for identifying the different species of tars separated previously ( 27 ) and a detector identical with the one of the first measurement line ( 26 ), a generator of calibrated tar atmospheres connected to the first measurement line and to the second measurement line, means for processing the measurements ( 36 ) from the first detector ( 32 ) and from the second detector ( 26 ), capable of comparing the data for each of the detectors ( 26 , 32 ) in order to indicate the total amount of tars measured by means of the first detector from measurements made with the second detector.
