AI Technical Summary

Problems solved by technology

But in a TA-GCMS setup, the time information related to the heating in a thermal analysis setup is lost in the column
[0005] In addition, the thermal decomposition reaction of the sample in the thermal analysis device has a width in the time direction, so if the generated gas is directly introduced into the column, sufficient separation cannot be achieved and only a wide chromatogram can be obtained.

Embodiment Construction

[0014] (1) Composition of the composite analyzer

[0015] Hereinafter, a composite analyzer and an analysis method according to an embodiment of the present invention will be described in detail with reference to the drawings. figure 1 It is a block diagram of the composite analysis device 10 of the embodiment. The composite analysis device 10 includes a thermal analysis device 1 , a connecting device 2 , a gas chromatography mass spectrometer 3 (hereinafter referred to as a GCMS device 3 ), and a control unit 4 .

[0016] The thermal analysis device 1 includes a heater 11 for heating a sample. The thermal analysis device 1 acquires information on mass change and differential heat of the sample by heating the sample with the heater 11 . In addition, the thermal analysis device 1 supplies gas generated by heating the sample with the heater 11 to the gas channel La. The thermal analysis device 1 includes a supply unit for a carrier gas, through which a gas generated from a sa...

Abstract

A combined analyzer includes a thermal analyzer, a trap, a gas chromatograph, a mass spectrometer, a first flow path to which a gas generated in the thermal analyzer is supplied, a second flow path that branches from the first flow path and is connected to the mass spectrometer, a third flow path that branches from the first flow path and is connected to the trap, a fourth flow path that connects the trap and a column included in the gas chromatograph, and a fifth flow path that connects the column and the mass spectrometer.

Description

technical field [0001] The present invention relates to a thermal analysis device, a gas chromatograph, and a composite analysis device of a mass analysis device, and an analysis method using the device. Background technique [0002] A combined analysis device (hereinafter referred to as TA-MS device) with a thermal analysis device (TA: Thermal Analyzer) and a mass spectrometer (MS: Mass Spectrometer), or a thermal analysis device and a gas chromatography mass spectrometer (GCMS: Gas Spectrometer / Mass Spectrometer) s Spectrometer) composite analysis device (hereinafter referred to as TA-GCMS device). [0003] The thermal analysis device included in the TA-MS device acquires information on mass change and differential heat of the sample during heating. In addition, the mass spectrometer included in the TA-MS device acquires information on the mass spectrum of the gas generated from the thermal spectrometer. In the TA-MS device, since the gas generated from the thermal analy...
