Abstract
A configuration is provided in which outside air is taken as a carrier gas into a carrier gas flow path (A, B). A CO2 sensor (specific gas detection sensor) (71) for detecting a CO2 gas desorbed from a sample is installed in a component gas detector (70). A CO2 sensor (air-containing specific gas detection sensor) (54) for detecting a CO2 gas contained in air taken into the carrier gas flow path by a blower fan (51) is installed separately. A CO2 gas detection amount detected by the air-containing specific gas detection sensor (54) is subtracted from a CO2 gas detection amount detected by the specific gas detection sensor (71) to calculate a detection amount of the CO2 gas desorbed from the sample.
Claims6
A thermal analysis apparatus including a heating furnace for heating a sample placed therein, a component gas detector for detecting a component gas desorbed from the sample by heating, and a carrier gas flow path for carrying the component gas desorbed from the sample inside the heating furnace to the component gas detector by a carrier gas, comprising:
- an air intake unit for taking in outside air as a carrier gas into the carrier gas flow path;
- a specific gas detection sensor that is provided in the component gas detector and detects a specific component gas desorbed from the sample;
- and
- an air-containing specific gas detection sensor for detecting the same gas as a specific component gas to be detected by the specific gas detection sensor from the air taken into the carrier gas flow path by the air intake unit, wherein a gas detection amount detected by the air-containing specific gas detection sensor is subtracted from a gas detection amount detected by the specific gas detection sensor to detect a detection amount of the specific component gas desorbed from the sample.
