<p>A method and device for automated non-destructive deterministic inspection of solutions in transparent containers (50) for particle contamination, comprising the steps of pre-positioning particles in a zone distance from the vertical spin axis, specifically by tilting of the container; rapidly rotating the solution container; suddenly stopping the container, wherein particles within the solution, continue in motion; illuminating (10) the container, while the particles are in motion, whereby particles within the container detectably (32) reflect or block light. The container (50) is tilted, prior to the spinning, by an acute angle ranging from 5 to 85 degrees, from a normal concentric vertical spin axis of the container, whereby effects of gravity are utilized to affect settling of particles to provide improved uniformity of spin energy transfer to the contaminating particles within the container, wherein tilting of the container, results in gravity providing sectoral positioning of the contaminating particles to the lowest portion of the container (50).</p> |
