Water absorption behavior of materials for biomedical application by HUM-TG

TA-1027: Water absorption behavior of materials for biomedical application by HUM-TG

 

Introduction

Organic compound such as α-Cyclodextrin and phyllosilicate clay minerals such as smectite and halloysite have been utilized as DDS (drug delivery system) and other biomedical applications with their structures shown below. Here, the STA8122 attached with a humidity generator HUM-1 was used to compare the water absorption and dehydration behavior of materials for biomedical application.

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.

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.
