Abstract:
1. A method for analyzing a powder sample of a substance, the method comprising: providing a powder sample of a substance in a sample holder that has at least one window that is substantially transparent to electromagnetic radiation in a selected wavelength region; performing at least one of vibration motion, rotation motion and translation motion (“motion”) on at least one of the sample, the sample holder and the at least one sample holder window at each of one or more selected motion frequencies, to thereby cause grains of the sample to move in a random manner relative to each other; directing electromagnetic radiation having a wavelength in the selected wavelength region (“incident light”) toward a portion of the sample shown in the at least one window; and for at least one selected motion frequency, performing at least one of a diffraction measurement, a transmission or absorption measurement, a reflection measurement, a fluorescence measurement and a spectroscopic measurement on incident light that has interacted with the sample, at a wavelength determined by a wavelength of the incident light.
