I asked this question about XRD analysis and it was answered very well. (https://www.researchgate.net/post/Is_it_essential_to_activate_MOFs_before_XRD_analysis)
Now I want to know for which one of others tests like SEM, FESEM, SEM-EDX, ICP-OES, ... we must activate or dry the sample just before test?
(If the sample takes up water quickly)
