ABSTRACT
This chapter provides an attempt to optical Raman sensor system to detect Bisphenol A (BPA) particles on quartz surface. The Raman sensor system was set up, comprising a butterfly laser diode, Raman fiber optic probe, spectrophotometer, and sensor chamber. Raman intensity is directly proportional to the concentrations when Raman intensity of BPA peaks has been enhanced with the increasing of BPA concentrations into surface. A Raman sensor was successfully self-developed by combining a few optical components in order to design an optical Raman system. The butterfly diode laser was acted as light source, fiber optic probe as an excitation light and a collection light path, and finally a spectrophotometer as a detector and an analyzer for the Raman sensor. The comparison showed that Raman system has successfully detected BPA particles only with a small percentage of uncertainty. However, the BPA sample position in the chamber is considered as a crucial role in order to get a high Raman scattering effect.
