Abstract
A process and apparatus for the qualitative analysis of particles of various kinds of plastic which comprises passing said particles serially in a predetermined path, irradiating each particle with light of short wavelength from 180 to 500 nm, whereby each particle emits light radiation of a longer wavelength, and detecting such longer wavelength emissions for radiation intensities within a narrow wavelength range to form an emission spectrum, the emission spectrum generating a sorting signal.
