AUTOMATIC SORTING OF POLYMER MATERIALS ON THE BASIS OF THE FLUORESCENCE DECAY TIME OF THE INTRINSIC FLUORESCENCE OF THE POLYMER AND OF THE FLUORESCENCE OF MARKING AGENTS

摘要

The invention relates to the identification of polymer materials on the basis of the fluorescence decay time of the intrinsic fluorescence of the polymer materials for definite sorting in a completely separated manner. The invention further relates to marking with fluorescent dyes, which, because of the specific fluorescence decay times of the fluorescent dyes, can further increase the sorting reliability by means of redundancy and can be used to identify particular batches.
