Abstract:
Since early 1970's the use of cold stage on SEM for observation of hydrated samples in their natural state has become more and more popular despite its high cost. Experiences gained from earlier experiments indicate that a successful design should incorporate the following features: 1. The specimen temperature should be below −135°C (the recrystallization point of water), lower the temperature, better the results. 2. The frozen specimen, the cold block in the specimen preparation chamber, as well as the cold stage should be kept under vacuum at all times to keep them frost free. 3. Different specimen preparation processes such as fracturing, coating and sublimation should be possible in one compact preparation chamber .
