Dear All,

Recently, I encountered a problem while plotting graphs for iso-conversional methods to evaluate the thermal behavior of biomaterials in an inert environment. I was able to see that at a particular value of conversion (alpha), with an increase in heating rate (5,10,15,200C /min), the corresponding T (alpha) is not changing or getting reduced. Prior to analysis, the TGA data was refined by data smoothing . Do I need to cover the alumina crucible with a lid while conducting TGA analysis or do I need to modify anything related to same. Kindly help me regard to this
