Can magnetic microsphere nano Fe3O4 be seen in SEM photos?

The magnetic microsphere nano Fe3O4 can be seen by field emission electron microscope. Click to view the product details.

Scanning electron microscope (SEM) imaging is to excite secondary electrons, backscattered electrons and other physical signals on the surface of samples by using finely focused high-energy electron beams. These signals are detected by corresponding detectors, and the intensity of the signals has a certain corresponding relationship with the surface morphology of the samples. Therefore, it can be converted into a video signal to modulate the brightness of the picture tube, so as to obtain the image of the surface morphology of the sample.

In order to determine the content of ferroferric oxide, a rapid determination method can be used. The test quantity for rapid determination of ferroferric oxide mainly consists of the following aspects: sample treatment, reagent preparation, instrument configuration and determination steps.
