Dehydration of Trehalose dihydrate by STA

TA-1035: Dehydration of Trehalose dihydrate by STA



Simultaneous thermal analysis (STA) is a method composed of thermogravimetry and differential thermal analysis that simultaneously measures the mass changes associated with endothermic or exothermic reaction. Generally, an open pan is used in STA measurements for volatiles to easily escape during mass losses which usually gives a broad and poorly resolved endothermic peak especially when a continuous dehydration reaction occurs. In this application, we demonstrate the influence of pan shape on the dehydration reaction of α,α-Trehalose dihydrate, a widely known material in food and pharmaceutical industry.

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



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

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

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.
