Hi,

Your graohs are quit confusing. But anyway i could say that fir graph. Better try with NETZACH German machines

1-62C

2- 33C

3- 75C

Lets verify with other researchers what they say.

Can you share the orginal pdf drived from your analyze machine? This one is so unclear. If you share that maybe i can help.

Abdul Al Lafi

the Tg does not show up as peak, but it is a step change. i.e. a change like the one next the numbers in your graph.

all the best

you can try take the first derivative of your DSC curves, then Tg will appear as a peak.
