PURPOSE:To perform the analysis of synthetic rubber within a short time with good accuracy, by automatically changing over the atmosphere of a heating apparatus from an inert gaseous atmosphere to an active gaseous atmosphere at predetermined temp. and correcting a componential ratio by using correction coefficient. CONSTITUTION:A heating apparatus 1 is filled with a synthetic rubber specimen being a measuring object. An atmosphere control apparatus 2 is operated to convert the atmosphere around the specimen to an inert gaseous atmosphere to heat the specimen at a temp. rising speed of 50 deg.C/min and the thermal change in the wt. of the specimen is measured by a wt. measuring apparatus 3. The temp. of the specimen is raised while the state change such as transformation or reaction of the specimen is detected by a detection apparatus 8 and, at the point of time of specimen temp. of 800 deg.C, the atmosphere around the specimen is changed over to an active gaseous atmosphere. Further, the temp. of the specimen is raised to about 1,000 deg.C to generate the decompositional combustion reaction of carbon black. The measured results obtained by the wt. measuring apparatus 3 and the detection apparatus 8 are introduced into an analyser 6 and operational correction is performed by using correction coefficient and the corrected values are recorded on a recording apparatus 7. |
