    • A method is disclosed for providing quality assurance in an industrial process. The method includes obtaining a manufacturing material from the industrial process, allowing the manufacturing material to contact with a nano-scale surface, which allows the harmful substance to adsorb to the nano-scale surface. The method also includes obtaining a Raman spectrum from the manufacturing material and the nano-scale surface using a spectrometer, searching for, using a spectral analyzer, a spectral signature of a harmful substance in a predetermined spectral region in the Raman spectrum to determine the existence of the harmful substance in the manufacturing material, determining the concentration of the manufacturing material if the spectral signature is found in the Raman spectrum, and rejecting the manufacturing material from the industrial process if the concentration of the manufacturing material is determined to be above a predetermined tolerance level.
    • 公开了一种在工业过程中提供质量保证的方法。 该方法包括从工业过程获得制造材料,允许制造材料与允许有害物质吸附到纳米级表面的纳米级表面接触。 该方法还包括使用光谱仪从制造材料和纳米级表面获得拉曼光谱,使用光谱分析仪搜索在拉曼光谱中的预定光谱区域中的有害物质的光谱特征,以确定存在 的制造材料中的有害物质,如果在拉曼光谱中发现光谱特征,则确定制造材料的浓度,并且如果将制造材料的浓度确定为高于预定值,则拒绝来自工业过程的制造材料 公差水平
