Effect of Sample Mass:

The sample mass affects the TG curve in subsequent

i) The endothermic reactions and exothermic of the sample will cause sample temperature to deviate from a linear temperature change.

ii) The degree of diffusion of evolved gases by the void space around the solid particles.

iii) The existence of huge thermal gradients throughout the sample particularly, if it has a low thermal conductivity.

Therefore, it is preferable to use as small a sample as probable depending on the sensitivity of the balance.
