Abstract: A thermal analysis device, a sample holder assembly and a thermal analysis method, capable of DSC measurement and TG measurement while simplifying replacement of a temperature sensor or the like upon damages. The thermal analysis device includes a sample holder assembly that is detachably mounted, a first sample stage and a second sample stage that are detachably mounted, a heater (heating furnace) that heats the sample holder assembly and the like, a temperature controller, a temperature measuring section for detecting a temperature difference between the sample and a reference substance, and a weight measuring section (balance) for measuring a weight difference between the sample and the reference substance.

Abstract: A gas analysis device and a gas analysis method for performing measurement in a direct mode and a trap mode without carrying out a complicated control. The gas analysis device includes a branching section that branches a target gas, a mass spectrometer performing mass spectrometry of one branched target gas, a trap section holding the other branched target gas, a gas chromatograph analyzing the other branched target gas, and a controller controlling the flow path of the one branched target gas and the other branched target gas. The branching section is controlled so that, while a thermal analysis is performed by a thermal analysis device, the branching section continuously branches the supplied target gas and discharges the one branched target gas and the other branched target gas, and when the thermal analysis is completed, the other branched target gas held by the trap section is supplied to the gas chromatograph.
