Abstract
Evolved gas analysis of polymers facilitates an understanding of the thermal behaviour and chemical composition of these materials. For the analysis of gases evolved from polymers both thermogravimetry (TG) and Fourier transform infrared spectroscopy (FTIR) and their combinations are well-established analytical techniques.
A hyphenated TG-FTIR technique has been developed with a unique interface system. The IR beam of a FTIR spectrometer is led directly into the TG equipment, the IR beam is reflected by a mirror mounted inside the TG equipment and is subsequently detected by the standard FTIR detector. In this “on-the-spot” technique the gaseous atmosphere directly above the sample in the TG equipment is monitored and IR spectra are collected as a function of time and temperature.
The experimental set-up will be presented together with a number of representative results in polymer research.
