Evolved gas analysis of edible oil by STA-MS

TA-2025: Evolved gas analysis of edible oil by STA-MS


Thermal analysis is a universal tool commonly used in a wide range of materials for physico-chemical characterization and for evaluating a material’s reaction to a specified set of conditions. Simultaneous thermal analysis (STA) hyphenated with evolved gas analysis is an essential technique relevant to reactions where there are mass losses and a simultaneous evolution of gases for qualitative identification of gases such as in thermal decomposition reactions or oxidative decomposition reactions, etc. In this application, we performed a qualitative analysis of the evolved gases during thermal decomposition of edible oil.

TG-DTA is a hyphenated technology generally referred to as simultaneous thermal analysis (STA).



DSC is a thermal analysis technique that quantifies the amount of energy in a reaction.

DSC with industry-first self-diagnostic feature and industry's highest temperature range

Quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature.

DSC8271 is a high-temperature type DSC with a maximum temperature of 1,500°C.

TMA is the measurement of a change in dimension or mechanical property of the sample while it is subjected to a controlled temperature program.


The compact humidity generator (HUM-1) is connected to the TG-DTA for measurements under constant relative humidity water vapor atmosphere.


TMA/HUM measures change in dimension or mechanical property of a sample while subjected to a temperature regime under water vapor atmosphere with a constant relative humidity.

In TG-FTIR, gases evolved by volatilization or thermal decomposition are qualitatively analyzed, which allows you to track changes in the generated amount along with the temperature change.
