Analytical Methods in Chemical Analysis
This chapter is in the book Analytical Methods in Chemical Analysis

Abstract

Thermogravimetric (TG) and derivative thermogravimetric (DTG) analyses are the most prominent and versatile techniques of thermal analysis that are developed and used to measure the variation in the mass (loss or gain) of a material sample arising through decomposition, degradation, vaporization, sublimation, oxidation, reduction, adsorption, desorption, etc., when a sample is subjected to the programmed temperature changes under controlled atmosphere. The chapter briefly describes the introduction of both the techniques, highlighting the differences between two. In practical aspects, the working principles of both the techniques and instrumentation have also been explained. The usefulness of the techniques in the quantitative estimation of calcium (Ca2+) and magnesium (Mg2+) in the sample mixtures have been covered in the chapter.
