What are the common instrumental factors affecting tg curves(short question)
Accepted Answer
Common instrumental factors affecting TG curves include:
- Heating rate: The rate at which the sample is heated can affect the shape of the TG curve. A faster heating rate will result in a sharper peak, while a slower heating rate will result in a broader peak.
- Sample size: The size of the sample can also affect the shape of the TG curve. A larger sample will result in a larger peak, while a smaller sample will result in a smaller peak.
- Gas flow rate: The flow rate of the gas used to purge the sample can also affect the shape of the TG curve. A higher flow rate will result in a sharper peak, while a lower flow rate will result in a broader peak.
- Crucible type: The type of crucible used to hold the sample can also affect the shape of the TG curve. A crucible with a high thermal conductivity will result in a sharper peak, while a crucible with a low thermal conductivity will result in a broader peak.
