G01N 23/00 - Definition fr

Definition statement

This main group covers:

Investigating or analysing materials by the use of wave radiation of very short wavelength (high energy), i.e. with a wavelength typically of a few nanometres or less, e.g. X-rays, including synchrotron radiation.

Investigating or analysing materials by the use of particle radiation, e.g. neutrons, ions or electrons.
