Discuss various sources of errors in TGA.

Thermogravimetric Analysis (TGA) is a widely used electro-analytical technique for studying material decomposition, stability, and composition by measuring changes in mass with temperature. However, several sources of errors can affect TGA results, leading to inaccurate data interpretation. These errors can be classified into instrumental, sample-related, and operational errors.
