Abstract: An impact-driven apparatus and method to achieve triboluminescence of homochiral API crystals as a measurement tool for rapidly assessing the presence of trace crystallinity within nominally amorphous pharmaceutical powders. The apparatus may include a kinetic energy director and two plates which hold a sample for testing. The triboluminescence may also be achieve by an acoustic transducer.
