How to use ZEISS scanning electron microscope for nanoscale analysis?
Date: 2025-10-28Read: 2
In today's rapidly developing nanotechnology, scanning electron microscopy has become an important tool for nanoscale analysis.ZEISS scanning electron microscopeWith its imaging capabilities and analytical functions, it provides strong technical support for researchers to explore the nano world. Mastering its usage is crucial for conducting high-quality nanoscale research.
1. Key steps in sample preparation
Careful sample preparation is the foundation for effective nanoscale analysis. Firstly, it is necessary to ensure that the surface conductivity of the sample is good. For non-conductive materials, conductive treatments such as metal spraying are usually required. The fixation and drying process of the sample should be handled with extra caution to avoid damage to the nanostructure during processing. According to the analysis purpose, it is sometimes necessary to perform special cutting or processing on the sample to exhibit specific nano features. The quality of good sample preparation directly determines the reliability of the analysis results.
2. Basic process of instrument operation
When operating, first place the prepared sample into the sample chamber to ensure that the sample is securely fixed. Then select the appropriate observation mode based on the characteristics of the sample. Before starting the nanoscale observation, preliminary focusing and astigmatism adjustment are needed to prepare for high magnification observation. During the observation process, special attention should be paid to preventing the sample from being damaged by excessive exposure to the electron beam.
