This datasheet demonstrates that the Epsilon 1, a benchtop energy dispersive X-ray fluorescence spectrometer, is more than capable of analyzing major, minor and trace elements in carbon nanotubes, in an easy and non-destructive way.

In the production of nanomaterials, catalysts are often used to enhance the formation of particles smaller than 100 nm. Nanomaterials are being used in many new applications. These include healthcare, composite materials, electrical and many other applications.
Catalysts that are commonly used in the production of carbon nanotubes are based on nickel, cobalt, iron, molybdenum, lanthanum or their combinations. Catalyst residues can cause major and minor unwanted impurities in the nanomaterials, which can affect their properties and therefore the final application. XRF analysis is a useful tool to monitor the impurities in the nanomaterials.
