Abstract
This invention provides methods and devices to measure particle suspension concentrations through the side wall of a container. Particle back-scatter readings are taken at light wavelengths that do not travel far through the medium. Detected scatter is related to actual particle concentration or standard O.D. values. The methods and devices allow particle concentration readings through containers not normally intended for use in such assays.
