| Abstract: | Spectrophotometry study of liquid-core optical fiber long-light-path has been done by theory and experiment method. Influence of light scattering and coupling on absorbance is analyzed. The relationship of absorbance with liquid-core optical fiber length, detected concentration, coefficients of light scattering and coupling is given. Experiment results agree with the theory. The method is proved to be a new trace analysis technology with high sensitivity and rapidly ailalytical velocity. Experimental apparatus and results are described and to be discussed. |
