Research on a new type of portable petroleum pollutants fluorescence spectrum detection system

Abstract

The ability to accurately and efficiently detect the contents and constituents of petroleum pollutants is important for environment of our ecological system. The fluorescence spectrum technology is applied to petroleum pollutants with high precision. A new type of portable petroleum pollutants fluorescence spectrum detection system based on multichannel sample cells and its optical structure is proposed. It is able to amplify the fluorescence signal without changing the volume of sample cell by increasing the optical path of the detection system using the parallel excitation of multiple microchannel sample cells. Through the experiments, it verifies the effectiveness of the microchannel fluorescence spectrum detection system and shows that the multichannel fluorescence spectroscopy has a stronger signal compared with general fluorescence spectrometer in the same experiment samples under the condition of the spectrum detection performance. It takes us one step closer to the realization of the real-time detection using fluorescence spectroscopy.
