    A procedure is presented for obtaining well-comminuted and uniformsize particles of nonbrittle samples for dispersion in KBr disks or for other applications for spectrum analysis. A range of nonbrittle materials including tobacco, biological samples, resins, paper, and other organic materials which present a difficult problem, particularly in infrared analysis, have been comminuted at liquid nitrogen temperatures, and their infrared spectra are presented and compared with those from other methods of preparation.
