PROBLEM TO BE SOLVED: To accurately and continuously analyze a trace amount of substance in high-temperature combustion exhaust gas, without depositing the trace amount of substance in the high-temperature combustion exhaust gas in the inside of a sampling line. SOLUTION: The high-temperature combustion exhaust gas 10 is cooled to 2300°C in a gas quick-cooling tube 16. The cooled high-temperature combustion exhaust gas 10 passes through a dust collector 18 to remove an impurity such as dust contained in the high-temperature combustion exhaust gas 10 therein. A heater 28 heats the dust collector 18 and the sampling line, and is regulated to make a thermometer 20 indicate 150-300°C. The high-temperature combustion exhaust gas 10 is guided to an analyzer 24 passing through valves 103, 105, and an organic aromatic halide is analyzed quantitatively/qualitatively in the analyzer 24.
