Application Note

Plasticizer Characterization by TG-IR Application Note

Introduction

Thermogravimetric analysis (TGA) is a common technique that is used to study the weight loss during heating. It can tell you the percentage of weight loss quantitatively and accurately. But TGA alone will not tell you anything about the chemical components of the evolved off gas. The hyphenation between TGA and FT-IR is able to identify the off gas from TGA and give a more complete picture of material characterization. The TG-IR hyphenation technique has been widely used for the polymer industry. This application note demonstrates how to combine the strength of TGA and FT-IR analysis to offers a more comprehensive material characterization.
