How the sample is prepared for SEM analysis in the case of a liquid sample?
Dear Dr. Mahato,
The analysis of liquids by utilizing SEM is possible to be accomplished by using some secondary tools. The more attractive way of acquiring SEM micro-graphs for liquid specimens is using vacuum compatible liquid cells. This type of wet cell SEM is also commercially available. The analysis of liquid specimens by utilizing SEM requires cell to high vacuum (Order of 10−6 Torr). Please find the attached file which I hope will be useful for you.

Liquid cells require BSE imaging, i.e. it is really suitable only for emulsions/suspencions.
Surface of water (and water solutions) is possible to observe directly in an Environmental SEM, but only surface.
If you do not need really high magnifications you may want to consider confocal microscope.
