Abstract: Objective : To establish a clustering analysis of microsphere by near-infrared diffuse reflectance spectrometry. Methods : Near-infrared diffuse reflectance spectroscopy combined with clustering analysis was used in the identification of microsphere. Results :The results of clustering analysis are obviously different,and the three samples of microspheres can be distinguished. Conclusions :This method is rapid,simple,low cost and can be used in the identification and quality control of microsphere.
