ABSTRACT:
A sample cell is described that permits the measurement of the light scattering properties of very small liquid-borne samples with negligible background interference form the illumination source. A technique is described whereby the cell construction permits the measurement of the illumination intensity at the scattering sample itself, permitting, thereby, the normalization of each detected scattered signal. The cell structure and detection method incorporated therein also permit measurement of extremely small angle scattered intensities without interference of the incident light beam itself.
