Cross-section SEM with freeze fracturing

A cross-section sample is prepared using freeze fracturing: samples are frozen in liquid nitrogen (-195 C°), followed by cracking of the frozen samples. The cracked surface is then imaged with a scanning electron microscope (SEM). In a typical measurement, several images with varying magnifications are taken to get a good overall view of the sample surface. The method is suitable for relatively thin and small samples. Appropriate thickness depends on the hardness of the material and the size of the samples but is typically < 1 mm. Feel free to ask our experts for guidance if you are unsure about the suitability of your sample.
