Cryo-SEM overview with the Quorum PP3010T

Many types of samples including but not limited to: ice cream, pastes, paints, and gels do not lend themselves to routine SEM sample preparation methods such as critical point drying or freeze drying due to the morphologic changes caused by desiccation. To avoid these artifacts, it is necessary to image the specimen in hydrated or natural state. This requires that the sample be rapidly frozen, to reduce ice crystal damage, and fractured to reveal their physical / functional sub-surface morphology.
