Comparison of nanoparticles in printer toners between original equipment manufacturer to office supplies manufacturer — •Paula Weber, Miriam Leifels, and Mathias Getzlaff — Heinrich-Heine-Universität Düsseldorf

We use laser printer toners in our everyday life. To identify its composition and the material properties we must examine it at the nanoscale. So we can, for example, observe a lot of different nanoparticles in printer toners. The differences between the various printer toner manufacturers in terms of nanoparticles relating to the size, the element composition as well as the various physical properties are remarkably.

This contribution will exemplarily discuss the comparison between the printer toner of original equipment manufacturer and the printer toner of office supplies manufacturer.

Different experimental techniques make the comparison possible. These include Dynamic Light Scattering (DLS), X-Ray Diffraction (XRD), Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM) and Energy Dispersive X-Ray Spectroscopy (EDX).

The sizes can be measured by DLS and electron microscopy. XRD allows to obtain information on the structure of the nanoparticles. The remaining questions can be answered by a specific SEM with integrated EDX.

By comparing the results of the various above mentioned methods, we get knowledge concerning the used nanoparticles.

Finally, the nanoparticles of the two different manufacturers are compared with each other to determine the similarities and differences.
