The behavior of water absorption and dehydration of organic compound α-Cyclodextrin

TA-5008: The behavior of water absorption and dehydration of organic compound α-Cyclodextrin

 

User can study the detail of influenced heating process of raw material by changing water vapor partial pressure in the atmosphere using TG-DTA connected to the humidity generator.

In the case of quantitative water in the material for thermal analysis (Constant heating method, Sample Controlled TG), it is available to measure each amount of water for adhered water and crystal water because of different of dehydration temperature due to the binding forces difference. On the other hand, if there are less difference of binding forces in each water, then it is difficult to perform separated determination because of overlapping of dehydration temperature.
