Elemental analysis is a process that determines the elemental composition of materials. In nanotechnology, this is crucial as the properties of nanomaterials can be highly dependent on their elemental makeup. Techniques such as Energy Dispersive X-ray Spectroscopy (EDS), X-ray Photoelectron Spectroscopy (XPS), and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) are commonly used.
