Noninvasive Detection of Concealed Complex Mixed Solution Using Raman Spectroscopy

Abstract:

In this paper, we present a modification Raman spectroscopic method-Spatially Offset Raman Spectrosocpy (SORS) for the noninvasive detection for the complex mixed soultion through diffusely scattering and fluorescing bottles and other packaging (including transparent, colored, diffusely cattering palstic and glass beverage, medicine and cosmetic bottles). Compared with conbentional Raman spectroscopic method, SORS is able to effectively supress fluorescence and Raman contributions originating from the container. This inherent ability cans substantially enhance the sensitivity. The application is demonstrated on the noninvasive detedtion of complex mixed solution. The experiments were performed using a 1064nm laser with 500mW average power, and a circular array of collection fibers were surround with the exciting laser. The resluts show that the SORS technology was capable of identifying the presence of concealed complex mixed solution in both transparent and non-transparen samples in quality control and authentication of chemical products.
