摘要： A method and apparatus for detecting and measuring organic materials present on components used in magnetic storage systems, such as an actuator coil. The component is heated on a hot plate, and a concave lens with a low surface energy coating is placed over the component. The contaminants volatilize and condense on the glass lens. The condensate is collected in solvent. The solvent is evaporated and the size of the residue is measured. A determination can be made whether the component is suitable for used in a magnetic storage system.
