⚠️ 5 Common Beginner Mistakes
- ① Fast heating blurring mass-loss steps
- ② Balance drift causing uneven baseline
- ③ Wrong atmosphere affecting decomposition
- ④ Inconsistent sample mass affecting results
- ⑤ Dirty crucible introducing error
❓ FAQ
+What can TGA measure?
Thermal stability, decomposition temp, composition and adsorbed water.
+How to choose heating rate?
Usually 5–20°C/min; lower for detailed study.
+Why inert atmosphere?
Avoid oxidation interfering with decomposition analysis.
