Preparing Sample Materials by Cryogenic Grinding

Cryogenic or cold grinding has proved to be the most ideal solution for these types of samples. This involves grinding aids such as dry ice (-78 °C) or liquid nitrogen (-196 °C) that are capable of embrittling the sample by cooling and making it break more easily. An additional advantage is that the volatile components of the sample can be preserved. This article describes which sample ...
