Hello everyone.
I am doing my research based on Dianhydride EDTA. As the DEDTA is highly sensitive to humidity, i put my sample in desiccator. For confirmation that whether my sample is stable or not, I did the FTIR. And the results showed that DEDTA ring structure is opened.
As there are other samples too in the desiccator (Sometiimes opening/closing of lid occurs), this time i put my sample in glass vial and tight the cap with para film. Before this i put my sample in falcon tube (May be if this could be a problem).
Your kind response will be highly appreciated.
Thank you,
