Dear Siti,

I found one paper that can help you with the DSC interpretation of the studied compound. You can get a meaningful information from your DSC run. See the paper attached:

http://www.scielo.br/pdf/eq/v29n2/22721.pdf

The authors observed the same peak as you did at about 240-260 C. They attributed it to the decomposition of sodium alginate. Hope this helps. Good luck!

Best Regards,

Andrey

Dear Dr Andrey E. Krauklis ,

Thank you very much for the paper. It really help me.

Furst heating is meaningful. Yiu shd not repeat the test fir the same sample. Because in the first heating the sample may undergo chemical reaction so you cant expect same out come in the second heating

Best

Dear Dr V R Arun Prakash ,

Thank you for your explanation. I will use this result as recommended.

Dear El-Houssaine Ablouh
