Item Summary for AMRAY 1830 SEM + EDX Electron Microscope

Amray 1830 Scanning Electron Microscope SEM + EDX for sale

Offered in AS IS working condition

The AMRAY 1830 SEM features a large specimen chamber and many accessory ports for future expansion of analytical capabilities.

Energy-dispersive X-ray spectroscopy (EDX) is an analytical technique used for the elemental analysis or chemical characterization of a sample. It is one of the variants of X-ray fluorescence spectroscopy which relies on the investigation of a sample through interactions between electromagnetic radiation and matter, analyzing X-rays emitted by the matter in response tbeing hit with charged particles. Its characterization capabilities are due in large part the fundamental principle that each element has a unique atomic structure allowing X-rays that are characteristic of an element's atomic structure to be identified uniquely from one another.
