G01N21/716 - CPC Classification

Classification description:

Investigating or analysing materials by the use of optical means, i.e. using sub-millimetre waves, infrared, visible or ultraviolet light; Systems in which the material investigated is excited whereby it emits light or causes a change in wavelength of the incident light thermally excited by measuring the radiation emitted by a test object treated by combustion gases for investigating the composition of gas mixtures
