100 pieces/box of 300 mesh carbon support film (copper mesh) for TEM sample preparation
When preparing most TEM electron microscope samples, in order to ensure that the sample can be mounted on the "carrier net", a layer of organic film is covered on the carrier net, which is called a "support film".
This kind of carrier net with supporting film is called "carrier net supporting film".
When the sample comes into contact with the carrier mesh support film, it will be firmly adsorbed on the film and will not slip off the holes of the carrier mesh for observation on the electron microscope.
When the sample is observed in the electron microscope, the "grid support film" will accumulate charge under the electron beam irradiation, causing the sample to discharge, which will cause the sample to drift, bounce, and the support film ruptures.
Therefore, people consider spraying carbon on the support film to improve the conductivity of the support film and achieve a good observation effect. This "carbon-sprayed grid support film" is referred to as "carbon support film", and its thickness is generally 7-10nm.
The carbon support film is mainly an organic layer, the film layer is thin, and the background effect is generally small. The sample is usually dispersed in water and ethanol, and the support film will not be corroded.
If your sample is a magnetic powder sample, you can use two methods:
1. Resin embedded, ultra-thin section
2. Can use dual networking carbon support film
