SEM sample preparation: how important is it to ensure the cleanness of SEM samples?
SEM sample preparation: how important is it to ensure the cleanness of SEM samples? Scanning electron microscope (SEM) is mainly used for microscopic morphology analysis. The quality of its test results is determined by the performance of the instrument, test conditions and the level of operators on the one hand, and is also related to the sample preparation process on the other hand. Scanning electron microscope (SEM) samples need to be kept clean and free of pollutants, and the pollution level should be reduced to a low level of zui as far as possible. Therefore, we are required to wear clean powder free gloves when taking and preparing samples, and keep the sample preparation tools such as scissors and tweezers clean. Keep the scanning electron microscope (SEM) sample preparation tool clean If you do not pay attention to keeping it clean during sample preparation, take the sample with bare hands, and the grease and dust on your hands will pollute the sample. As shown in the figure below, after bare hands touch the clean aluminum foil surface
