Qualitative analysis of biopolymer in humidity atmosphere by HUM-STA-MS

TA-2032: Qualitative analysis of biopolymer in humidity atmosphere by HUM-STA-MS

 

Introduction

Biopolymers are known to be sensitive to moisture conditions during storage where continuous exposure to humidity causes hydrolysis in the material. In this application, we demonstrate the use of humidity controlled atmosphere (HUM-1) in STA connected to a GCMS system to detect changes in thermal decomposition behavior and evolution of gaseous compounds in Poly-D,L-lactide as affected by water vapor atmosphere.

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.
