A technique for rapid determination of the presence of polystyrene in individual micron‐diameter polymer particles of mixed composition is presented. This technique is based upon observation of visible emission from conjugated regions of the polymer backbone, generated photochemically, while the particle is held in an optical trap. Particle emission characteristics are dependent upon particle size and suspending solvent. Emission spectra are provided for single component polystyrene particles and mixed polymer particles containing poly(methyl methacrylate), poly(N‐vinyl pyrrolidone), and polystyrene. © 1998 John Wiley & Sons, Inc.
