How to fill out tem specimen preparation techniques

How to fill out TEM specimen preparation techniques:

1. Prepare your TEM grid: Start by selecting a suitable TEM grid, such as a copper or gold grid. Clean the grid using a suitable method, such as sonication or plasma cleaning, to remove any contaminants. Ensure the grid is dry before proceeding.
2. Sample preparation: Prepare your sample for TEM analysis. This may involve slicing a thin section from a larger sample or preparing a thin film of the sample material. Ensure the sample is representative and free from any artifacts or impurities.
3. Embedding the sample: Embed the sample in a suitable embedding medium, such as epoxy resin. This helps to stabilize the sample and enhance its contrast in the TEM. Carefully position the sample on the TEM grid, ensuring it is properly oriented if necessary.
4. Thin sectioning: Use a microtome or similar instrument to slice ultra-thin sections of the embedded sample. The thickness of these sections should be in the range of tens to hundreds of nanometers, depending on the specific analysis requirements.
5. Staining (optional): In some cases, staining may be necessary to enhance the contrast of the sample in the TEM. This can be achieved by applying a suitable stain, such as uranyl acetate or lead citrate, to the sample. Follow the appropriate staining protocols and ensure proper rinsing to remove any excess stain.
6. Sample drying: Allow the sample to dry completely before loading it into the TEM. This can be done by air drying or using a desiccator. Ensure the sample is handled carefully to avoid any damage or contamination during the drying process.
