Fernando Vallejos-Burgos

Freeze drying the sample should help you to avoid re-stacking of the platelets.

After this, you should heat up to some 150 degC at high vacuum for degassing.

Doufnoune RACHIDA Rachida

Hi;

The sample should be lyophilized. You should also degas your sample for at least 16 h at a low temperature so as not to alter your sample.

With my best regards
