Quizplus · Accepted Answer

The solvent in an SEM specimen's cells is usually replaced with a liquid transitional fluid, usually CO2, that has been vaporized under pressure. This process is called critical point drying and it removes the solvent without causing significant distortion to the specimen. Glycerol, serum, and hydrochloric acid are not commonly used as replacement solvents in SEM specimen preparation. Water can be used for some types of samples, but it can cause shrinkage and distortion in other types of samples.
